Is Global Warming Real? You’ll Find Your Own Answer

By Anupum Pant

In the year 1964, the surgeon general of U.S. Public Health Service released a comprehensive scientific report that linked cigarette smoking to several deadly diseases. Of these diseases, the worst were lung and laryngeal cancer.

Even after 10 years from when this report was released, the real dangers linked with cigarette smoking could not reach the public. And even today, after having killed 100 Million people in the last century, not everybody believes that this deadly habit, really is a deadly one. There was a reason for that…

In the face of all the scientific evidence and reports, people were still being convinced to smoke, by elaborate campaigns. Before 1964, the ads promoting smoking were too absurd. But, even after 1964, when the report was released, this propaganda did not stop. In fact it blew up, as if to cover up the scientific evidence, as if to nullify the findings of the report, to seed a doubt, and to keep the public from recognizing the truth. People were being coaxed to smoke.

Fake science

Fake science was being conjured up to disprove the findings of the 1964 report. A doubt was being created in the minds of the public. The tobacco industry, a flourishing one, was funding various institutions to create fake studies that create a doubt in people’s minds. These were real scientists who were being paid to speak.

And now people started thinking that there was an actual debate going on between scientists. They thought, since scientists weren’t too sure about the harmful effects, they need not be careful with cigarettes.

Dr. Fredrick Seitz was one big player in this. He was a founding chairman of the George C. Marshall Institute. The job of people at this institute was to popularize cigarettes (or tobacco) by creating a doubtful atmosphere, saying with phony scientific studies, that the scientists who said cigarettes caused cancer, were not really sure about what they said.

The same institute ran several campaigns against the dangers of other actually dangerous things like acid rain, ozone depletion and DDT. They said acid rain, ozone depletion and DDT weren’t really harmful. In return, they were being funded big bucks from major businesses.

Their campaign against the dangers of cigarettes delayed the response of general public by a decade. Roughly, you could even say that this very campaign was one reason that caused 10 Million deaths. They probably weren’t happy that their fake science was killing masses. But they were getting paid well. Wasn’t it a massacre?

The Next Big Thing

Pro-cigarette and others were relatively smaller campaigns. Now, they were on to something big. This time, it was the largest conglomerates – Petroleum industry – in the world who wanted to fund the institute to create phony science that would create a doubt about global warming. The petroleum industries did not want their industry to collapse after the real science came out with results that could hurt them. They wanted to create a delay in the response from the public. Just like the decade’s delay which happened after the 1964 report.

This time the lives of millions are not at stake, it’s Billions.

Now do you really think  that global warming is a delusion? Are scientists really doubtful if the world is getting hotter? Or a fake doubt is being created by the likes of George C. Marshall Institute.

Here is the video which educated me about it:

You probably have your answer.

There is no doubt. Global warming is real. The doubt that is being created is a phony one.

A Thread Around the Earth

By Anupum Pant

Background

Couple of days back, I read about a puzzling geometrical conundrum, probably on Quora. It might not sound amusing to you math geeks out there, but to me, it sounded like an impossible thing at first. The sad part is, I did not save the source link in my notes. Thankfully, I did care to note down the idea. Let me call it the “Thread wound Around the Earth” puzzle.

Here is a simple question first. Try answering it without any calculation. Just guess. Be honest to yourself, don’t see the answer just below it. Scroll slow.

As BBC’s website puts it…

Imagine a piece of string wrapped around the Earth’s equator – that’s about 40,000km. How much MORE string would you need for it to sit 15cm above the ground, all the way around?

A) 1 metre, B) 1 kilometre or C) 1,000 kilometres

Thread wound around the Earth

The answer is A) 1 meter. Yes, just 1 meter of extra rope.

Suppose, you have an outrageously long thread with you. You tie it around the base of a tree, somewhere at the equator. Now, you go around the earth, along the equator, carrying the thread with you, till you come back to that tree where you started. At this point, you’ll have a thread that goes around the earth in a circle. At every point, let us imagine that the rope is taut and touching the ground (there are no mountains or valleys in between). It’s a perfect circle (assume).

Suppose, you still have an extra meter of the rope left now. So, you break the wound rope at one point and add the extra meter to it. That of course slackens the wound rope. For this rope to be taut again, it has to be lifted up by some amount. What do you think that distance would be from the ground? Assume that the rope still makes a huge circle just above the ground and lifts by equal amount at every point along the equator.

Just the extra meter of rope, causes the rope to rise by ~15 cm all around the earth (actually 15.9 cm). For a single meter of rope added to a 40,000 km of rope, that sure seems like a huge lift! But that isn’t all…

rope 15 cm above earth

The most amazing part is that, no matter what the size of the circle, a meter of increased circumference will increase the radius by ~15 cm. Always!

Try tying a rope around a golf ball, or even try doing that around the sun. It’s always that – 1 meter increase in circumference, always increases the radius by ~15 cm.

The Math is so straightforward.

If you think about it mathematically, it is completely straightforward.

Radius X 2 X Pi = Circumference

That means, the Radius is directly proportional to the circumference of a circle. Everyone knows that. So, the amount of change in the radius is reflected proportionally in the circumference, the magnitude of radius can be anything, really. So it’s pretty natural that just a single meter of rope is required to lift the rope by 15.9 cm around any circle. The size doesn’t matter. But practically thinking, the above question makes it seem impossible.

Is Helium Beer Possible?

By Anupum Pant

Background

For the fizz, almost all beers have carbon dioxide dissolved in them. However, some others have also experimented with Nitrogen beers. But as fas as I know, no other gases have been used to make beers. Tell me in the comments section if you know any other gasses that have been used to do this.

But, on April 1st  Samuel Adams announced a Helium beer on his YouTube Channel. Note, the date was 1st  April. Here is the video of the announcement.

Save Helium and Science of the Fake Beer

Of course it was an April fools stunt. But what if it was real?

In his “HeliYum beer” Adam announced that, instead of carbon dioxide to create the fizz, he had used the Helium gas in the beer. In the video, as an additional effect, the new beer gas also created a funny atmosphere by affecting the voice of beer tasters. Now, I certainly didn’t like the idea of using Helium to keg beers because I’m very touchy when it comes to wasting the precious gas – Helium. Why? Well, read this Helium article I wrote some time back.

Also, I was adamant in believing if it was even possible to do that. Firstly, the date was 1st  April. Secondly, the science clearly didn’t allow this. Here’s why…

1. Helium is about 700 times less soluble in water as compared to carbon dioxide. It is one of the least soluble gases in water and only about 0.0016 g of Helium would get dissolved in a litre of beer. While, at the same conditions, 2.5 g of carbon dioxide is usually present in a litre of beer. This dissolved carbon dioxide is what realeases slowly and creates the fizz. No slow fizz can be done with Helium. Undissolved helium in beer would coalesce into one or two big bubble and…ploop, would go out as soon as the seal would break.

2. Even if Helium was forced into the beer and sealed in a beer can, it would be useless. As soon as the seal would break, all the meaningful amount of helium present inside, undissolved, under pressure, would come out so quickly (due to less viscous beer) that it would bring out a lot of beer with it. It would create a mess. And you wouldn’t be able to even bring the can near your face by the time the whole gas goes away.

Had carbon dioxide been used for the same purpose, the gas would, like it normally does, come out steadily. It would make the bubbles last.

Verdict: No. It’s useless to try to make beer with Helium unless you make it so viscous that it won’t let the Helium pass so easily. In that case, it won’t be beer really. Also, I’m not sure if the fermentation process could take place in such a viscous condition.

Seeing With Your Tongue and Listening to Colour

By Anupum Pant

I’m always fascinated when I see one sense organ do the work of some other sense organ. Like breathing from your eyes ( not really) or seeing with your ears (really) listening to colours etc…

not available in your country

Solving The Technical Problem (Not available in your country): Today, I stumbled upon a video whose title was “Blind Learn To See With Tongue“. It was uploaded on YouTube by CBS – an American TV network. The sad part is that they had tweaked the videos settings which did not allow me to watch it. It wasn’t available in India.

Whenever someone says I can’t do something, I’m almost always prepared for it. This time, I had this extension installed on Chrome called ZenMate. It’s perfectly legal (available on chrome store) and works very smoothly. It allows you to surf the internet with total control. With it installed, you can totally forget about your physical location and fool the websites which place a location restriction for access, like Spotify and Youtube’s “not available in your location” videos. I haven’t tried other things but it should allow Indians to access stuff from websites like Hulu, Pandora and Netflix. (Even if it may seem out of place, I wasn’t paid by ZenMate to write this. I really recommend it.)

The Customary David Eagleman talk

Now, whenever I come across something that has to do with seeing things with an organ that is not really meant for seeing, I remember this very-old TED talk by David Eagleman. And I like to attach it to my blog because I can’t really explain this amazing ability of the Human brain as well as he does. He basically segues his talk to discuss how brain can learn to interpret various kinds of signals to produce an image. So, here it goes. Watch it and read on…

Since it is clear that seeing is the ability of the brain, not eyes, we can comfortably move on to see how you could even see with your tongue – Tasting the light.

Seeing with the Tongue

A device called BrainPort can help you do that. The contraption consists of a camera that sits on your forehead and sends information to a small computer. The information is processed, converted into electrical pulses, and then sent to an array of electrodes touching your tongue. The brain processes these signals and converts them into an image.

At first, of course the brain doesn’t know the trick to process visual signal from the tongue, but it learns. Gradually the device becomes a part of your body and you start seeing with your tongue! Just like Neil Harbisson can listen to colour. In fact, he can see more colours than our eyes can see because the technology allows him. He can see infrared and ultraviolet too!

The Sweet Tale of the Mysterious Tree Lobster

By Anupum Pant

I do realize how big our world is and the sheer number of species that live in it. Also the fact that about 86% of the species are still unknown has me in awe all the time.

Yet, after having read about so many kinds of animals that live on our planet, after having documented them on this blog, I always feel that I’ve known and written it all. The very moment I start losing hope that I would never find an interesting animal ever again, something incredible comes across. Always!

Today, that happened again when I was reading an NPR blog. This time, there’s more than the species itself. The place where it lives is pretty awesome too. The most amazing part – This six-legged giant lives only there. That means, nowhere else on Earth will you find it! First, let’s see where it lives…

This is where it lives:

balls pyramid

I know, it looks like a CG mountain done for a fantasy movie. Trust me, it’s real. It’s called the Ball’s Pyramid (named after a European named Ball who first saw it in 1788) and was formed 7 million years ago due to a volcanic eruption. It is an awkwardly tall (1,844 feet) and an extremely narrow rock sitting in the centre of the sea. To the East of Australia, the red place marker in the following picture shows where the rock is located.

balls pyramid location

 What lives there? And how was it found?

There is an island – Lord Howe island – close to the rock. In the island lived huge “tree lobsters” (actually they were huge stick insects with a hard exoskeleton – Dryococelus australis). In the year 1918, a ship crashed on the island and brought with it some rats. The rats loved these tree lobsters and finished them off within 2 years. After 1920, these tree lobsters were thought to be extinct.

tree lobster

Of course there were stories of these insects living on a rock near the island. But no human wanted to climb the narrow rock to hunt insects at night.

Only in the year 2001 when 2 researchers David Priddel and Nicholas Carlile decided to climb up the rock to find out if these stories were real, they found something incredible. Poop of a large insect. When the came back at night to investigate, the shiny black huge tree lobsters were found! These insects had probably never been extinct.

For more than 80 years, 24 of them had been living on this rock, in a bush and no one knew how they got there. Probably they clinged on to birds or something. Also, according to the researchers, these creatures have never been seen anywhere else.

Where are they now

I’m not sure about where they are now. According to the 2012 NPR article which I read, a pair of these creatures – Adam and Eve – were brought into Australia. Eggs got laid and little Tree lobsters came into the world. Thankfully, the species was saved from going extinct. But it isn’t known if they’ll be sent back to their home island because the great-great-great grandsons of those rats must still be there waiting to finish these insects off again.

This is how the first ones hatched in the zoo…

Carrots Don’t Really Make your Eyes Better

By Anupum Pant

I have been lied about taste areas on the tongue, gas station & cellphones and what not! I feel everything I have ever known is wrong. And here we have one other myth that got busted today. I always thought was true. Thanks to the following Vsauce video (0:28 seconds) which opened my eyes and sent me to research on this topic.

I was so sure about carrots helping your eyesight that I had never questioned this belief. My parents told me, the doctors told me, my teachers and every one else (even Kawaii) told me.

Eat more carrots. Carrots will improve your vision.

eat more carrot kawaii

The truth about carrots

The truth is, carrots of course are good for the health of your eyes like any healthy diet is, but they don’t improve your vision. You won’t start seeing in the dark if you eat more carrots. Your normal diet gets you enough of vitamin – A to keep your eyes healthy. Carrots do no extra magic.

Carrots contain a substance called beta-carotene, which gets converted into vitamin – A and as everyone knows vitamin – A is good for your eyes. Of course the lack of vitamin – A in your diet could land your eyes in a problem. But you normally get enough of it through a normal diet. You don’t need carrots to keep your eyes disease free. Any more of vitamin – A supplied by carrots isn’t going to make your vision better. 

What is more interesting is how this propaganda started…

The Interesting Myth Origin

Turns out, “carrots make you see better” was a widespread World war II propaganda, clearly a bold faced lie which was used to save London from the tyranny of Nazi. It probably did better than the best email scam ever. The lie blew up, and today it has reached almost every living kid. I’m pretty sure even textbooks mention this.

During the WWII, the Royal Air Force started using radar to spot Luftwaffe bombers at night. But they wanted to keep this trick of their’s a secret. To achieve secrecy What did they do? They started a propaganda.

A story came into existence. According to it, a very skilled British Pilot, “Cats’ Eyes” who ate a lot of carrots, had developed a night-vision of sorts, and had gained the ability to spot German bombers at night by just tweaking his diet habits. British civillians loved the story and started eating more carrots. They thought it would improve their vision and they’d start seeing at night. The story spread like wild fire. Who would have known that the Cats’ eyes story was a propaganda issued by the Navy to conceal their use of radar technology.

The propaganda of course did save London.

Too much of anything is bad

FYI: Like too much of anything, even too much of Vitamin – A can be toxic. Deaths rarely happen due to this. But, they do!
Also, eating too much carrot may overdose your body with beta-carotene and could cause Carotenemia. As a result, your skin would turn yellow. It looks like jaundice, but it’s harmless and easily reversible.

World’s Most Relaxing Music and a Trick to Waking Up Happy

By Anupum Pant

Warning: I like to boast in public because it helps me stick to my resolutions better. Following is a paragraph that brags a bit, so please understand…

Phew! It’s been 179 days since I started this website and there isn’t a single day I’ve missed writing something here. Some days the articles were good, other days they were awful. Good or not, at least I slept a little smarter everyday. As a result, I have documented 179 good pieces. You can check them in the archives right now. Be my guest and since it is sunday, take some time to read through some of them, find mistakes, comment etc.This, thankfully, is the 180th article that is being written on the 180th day. That’s pretty huge for me. I’ve never done something this big ever in my life before. Trust me, it is a very tough commitment. If you wish to, acknowledge it in the comments. It will mean a lot to me.

However, today due to some other important work, my article writing ritual got delayed (happens a lot), and now it’s more than an hour past midnight. Thanks to my public boasting, I will still have to keep up. No sleeping before I write something. Or, I will simply have to get shamed in public (if someone even keeps a track of my progress). Probably my sleep will have to suffer today. So I thought, to sleep efficiently, let me learn a bit about sleep!

59 Seconds again!

And as always, the YouTube channel 59 seconds came to my rescue. I love the channel so much, I’ve mentioned it in at least 5 different posts before.

Anyway, the host, Richard Wiseman has a new book in the market – Night School: Wake up to the power of sleep. It talks about the science of sleep. Whenever he has a new book, there are a few interesting videos that come up on his channel that share a very cool tidbit from the book. The book is definitely on my read list, but will have to do with a related video for now.

World’s Most Relaxing Music

One of the videos this time is one hour-long and plays a scientifically constructed music that according to the professor is the world’s most relaxing piece of music. If you keep playing it in the background while sleeping, it will help you sleep better. I’ve tried this one when I took a nap in the afternoon one day. I can vouch for it. I actually had a very relaxing nap that time.

The tune is especially relaxing because, with a 90 BPM tempo and notes moving from low to high, it is scientifically designed to help you fall asleep. Here is the piece. Play it and have a good sleep.

While this would help me fall asleep, tonight I won’t have a problem with falling asleep. As I’m tired, I’d fall asleep easily. What I’m worried about is that I might get less sleep (it really doesn’t matter, I can just wake up late tomorrow). So, here is something from the same channel that, even with a shorter sleep span, would probably help me wake up happier tomorrow.

The 90-Minute rule

During our sleep, we have these cycles where our brain takes us from light sleep to deep sleep and then to a dream state. These three states make one cycle and it takes about 90 minutes to complete a cycle. If you happen to wake in the middle of a cycle, you’d wake up cranky. The trick to waking up happier is to wake up when one of this cycles is complete. There are of course apps on the Play store that help you achieve that, but I don’t have an android phone. So here is what I can do.

I can plan an alarm in a way that I complete several 90 minute cycles and wake up at the end of the last cycle. For that, if I plan to fall asleep at 2:30 AM, to complete a fair 6 hour sleep, I’d have to put an alarm for 8:30 AM. At 8:30, I’d have completed 4 cycles.

Except that these cycles don’t last for exactly 90 minutes. Some times they are more than that, other times they last for a lesser time. Still, by measuring my sleep period in 90 minute chunks, I can increase the probability of me waking up happier. Here is the video where Richard explains this…

Walking from Cape Town to Buenos Aires

By Anupum Pant

You could theoretically walk from cape town in South Africa to Buenos Aires in Argentina. No, I’m not talking about you walking on the deck of a cruise liner while it’s sailing across the South Atlantic ocean. I’m talking about a really really long walk on land, that would require you to walk to Argentina from the other side of the globe!

This is the path you could take if you are adventurous enough –

cape town to buenos aires

Winter time: If you ever plan to do that, remember to plan your journey in such a way that you get to cross the Bering strait during the winters.

Since the land masses are separated by sea, it won’t be possible to cross it on foot. But during winters, when there a couple of chunks of ice floating around, you could theoretically jump from chunk to chunk and complete your almost impossible journey. Two things to remember would be that it is illegal to do that and is extremely dangerous too. Read on to know why.

Bering Strait: At the closest distance, the mainlands of America and Russia are just 85 km apart. The main lands are separated by the Bering strait. But the 2 seemingly distant countries get much closer to each other at edges of these 2 islands in between the Bering strait – The Diomede islands. Separated by just about 4 km, one of the islands is in Russia while the other is in America. A date line passes from right in between the islands and the times one island is 23 hours ahead of the other.

bering strait

During winters the parts of Bering strait freeze and they have huge chunks of ice floating around. But almost always, even during winters, there is a very strong current of water flowing across the Bering Strait. If you are lucky enough, the top part could get clogged for some time due to big ice chunks and could allow you to walk across to Russia, from Alaska.

In fact, people have done it in the past. In the year 2006, two friends Karl Bushby, and his friend Dimitri Kieffer were able to walk across the Bering strait from Alaska to Russia. They were immediately detained and deported for entering the country illegally. Most other attempts have ended fatally, involving rescue teams almost every time.

On November 1, 1998, at the age of 29, Bushby began walking from Punta Arenas, Chile at the southern tip of South America. Everything he owned was in a makeshift trolley called “The Beast.” He only had $300 in his pocket. Since then he has traversed the entire length of South and North America, completed the first recorded crossing of the Bering Strait on foot and progressed two thousand miles into Siberia. His goal is to finish the remainder of his journey across Asia and Europe back to England. To date, he has walked 20,000 miles of the 36,000-mile journey over the course of 15 years.

Even crossing this strait on a boat could prove to be dangerous as you’d be bombarded by intense storms constantly. And of course you’d end up in jail for attempting it. There is also no chance you are getting a legal permission to do it.

In short, provided you cross it in winter, have the ability to survive wind chill temperatures up to -100 degree C, are ready to risk your life and are ready to face legal consequences, you can cross the Bering strait and literally walk across from America to Russia.

In addition, if you are sure you can walk for several thousands of kilometres to make a one of its kind journey, you could actually walk from Cape Town to Buenos Aires.

Stone Age Technology Still Makes the Best Blades

By Anupum Pant

Normally, the electric shaver gets the work done. So, I almost never  have to use a fixed blade razor for shaving my facial hair, but after seeing this, I think I should start using a fixed blade. Here is a highly magnified image (using a scanning electron microscope) of two strands of hair. The left one was cut using a fixed blade and the right one was cut using an electric razor. See the difference for yourself.

magnified image of Hair cut using a fixed blade and electric shaver

 

So, even if the major thing that causes a messed up strand is due to the fast moving blade of an electric razor, but one other important factor is the sharpness of the blade. The point is, electric shaver blades aren’t too sharp, while fixed blade steel razors are pretty sharp. Thus, the steel blades can give you a clean cut.

Still, when it comes to fine tools, steel blades stand nowhere. Look at what a Gillette blade looks like when its put under an electron microscope (at not even a very high magnification – 150x).

Gillette_Blue_Blade_150x

Yes, even those seemingly perfect Gillette blades can be that jagged under high magnification. Thank goodness, blades can get much finer.

Obsidian Blades

Obsidian is a naturally occurring black volcanic glass. A glassy rock, you could say. It is very hard and of course, like most hard things are, it is brittle too. So, if it isn’t handled with good care, it breaks pretty easily. Yes, that kind of a rock.

When it breaks, it forms very sharp edges. These edges can sometimes get much much sharper than your normal steel blades. Also, even if they are brittle, they are pretty durable in a sense that they can hold their edge for much longer times. These were the reason, our ancient palaeolithic ancestors used to chip these rocks and made them as the tips of their spears and arrows.

Blade edges made out of obsidian are so sharp that they don’t seem jagged even when seen under an electron microscope. Their edges, if made carefully using processes like pressure flaking process, can get up to 3 nm thick. Good quality blades can make cuts down to single molecules! That is about 500 times sharper than the sharpest steel blade.

Left: Obsidian tip under and electron microscope. Right: Steel point under an electron microscope.
Left: Obsidian tip under and electron microscope. Right: Steel point under an electron microscope.

While blade edges made out of obsidian are not approved by the FDA, surgeon scalpels are still made using them. Studies say that cuts made using these blades get healed much faster than the ones made by steel blades because obsidian blades can make extremely narrow cuts between the cells, and not tear the cells apart.

Lee A. Green, associate professor of family practice at the Medical Center, uses obsidian knives for removing moles and repairing torn earlobes. – Source

Of course synthetic diamond blades have been made. But obsidian blades are still better in terms of durability.

Stone age technology is still the best.

Planarian Worm – Cloning a Creature was Never This Easy

By Anupum Pant

Lizards grow a new tail if the old one is lost. In fact, they even shed it of voluntarily to save themselves from predators. Then start fish can grow their cut arms back, earthworms can grow back cut parts too. Even Axolotls are pretty good at regeneration. But there is probably nothing as strange as the Planarian flatworm.

If you happen to slice a Planarian worm into half, vertically (or any other way), both the parts will regenerate! So, in 2 weeks you’ll have 2 Planarian worms cut out of a single one. The ability to regenerate is so good that even if a 1/300th part of this worm is cut, the small bit of it can regenerate the rest of the worm! But that isn’t even the strange part.

Now, naturally, since it can grow back its body, it can grow back its head too. But the most amazing part is that with the new head, the old memories of the flat worm also come back! That is strange, isn’t it?

With just a knife in your hand, cloning was never so easy.

Fun Fact: Planarian Flatworms also do not have a separate anus. But they do have an cavity at the rear end which they use to take in food. The same cavity is also used to send out the waste stuff.

Do Not Paint Your Walls Pink

By Anupum Pant

Like I’ve told you once, there is no pink. Still, we do see the colour pink and there’s no denying that. Don’t call me a sexist for saying this, but it’s true that the colour pink is associated with femininity. Otherwise the colour is also known to generate feelings of caring, tenderness, and love. If everything we know about pink is somewhat positive, then why isn’t it a good idea to paint your walls pink?

Let me start with a little story.

Hayden Fry and the Pink room

Hayden Fry was an American football player and later he went on to become a coach. In the late 70s he started coaching the University of Iowa football team. Now, the particular thing to note about Fry was that in the year 1951 he had graduated from Baylor with a degree in psychology.

Since he had graduated in psychology, Fry probably knew some good ways that he could use to mess with the opposing team’s brain. And then he decided to paint the walls of the visitor’s locker room at Iowa’s Kinnick Stadium, with the colour pink. The walls, floors, toilets, ceiling and everything else in the locker room was painted pink. As a result, the home team started doing significantly well at football games (later the practice of painting locker rooms pink was outlawed).

Some say, he used pink to paint the visitor’s locker room because he knew that the colour pink had a calming effect on people. But I think he was relying on something deeper. He was probably trying to cash on the results of a study that was done by Prof. Alexander Schauss in the year 1979.

The Effect of Pink Colour

Prof. Alexander Schauss started a study with a couple of volunteers. He divided the group into two equal halves. All of their strengths were measured by asking them to use their arms against a counter-force and by asking them to squeeze a device called a dynamometer.

After this, for a minute, the first half had to stare at a dark blue colour and the other half stared at pink. Their strengths were recorded again.

A remarkable decrease in physical strength was recorded among the people who were given the colour pink to stare at. The participants were not aware of the effect it had on them.

Probably it were those pink walls and pink floors at the visitor’s locker that made the opposing team physically weaker and helped Iowa win.

Conclusion

Colours certainly are one of those subtle forces which change the way we think, feel, and behave. Pink has been proven to make you weaker physically. So, unless you wish to be weaker, you wouldn’t want to paint your walls pink! How about blue? It is a simple choice.

Now I think even writing an article about pink and having your brain think about the colour makes you weaker. Seriously, I feel like I need rest after writing this. Phew!

Scientific Ways to Make Cut Flowers Last Longer

Suppose, someone gives you a beautiful bouquet, celebrating a very important day of your’s, say your 50th wedding anniversary – A rare event these days. Wouldn’t it make you happier if these precious flowers last longer, even if it is just “slightly longer”? If you are a person like me who is easily moved, seeing flowers last longer would certainly make you happier!

Here are a few simple scientifically proven ways you could try that would make your cut flowers last slightly longer.

Well, to make a flower last for about 3 days,  of course you could cut off an inch of the stem, clean it and put it in plain water. But there is also a little addition you can do to the water to keep them blooming for a few more days.

Add some amount of sprite or 7-Up to the water. Yes, that’s it. I know, some would consider it an urban legend or a forwarded email story, trust me, it actually works. Continue reading Scientific Ways to Make Cut Flowers Last Longer

Wood Frog Dies and Comes Back to Life

By Anupum Pant

Ice Kills

Everybody knows what extremely low temperatures can do to our body. If you aren’t well protected from the cold, unable to retain the heat, the core temperature of your body may drop below 35 degree C and can cause some serious problems, even death.

At even lower temperatures, ice crystals can form in the tissues and puncture blood vessels. Ice crystals may even squeeze, deform and break cells. Otherwise it can leave behind shrunken and destroyed cells by sucking out water from them to form ice. Probably leaving you with a permanently damaged body part.

Due to ice formation inside the cells, this disastrous structural damage that is caused in human bodies, or most other organisms is unavoidable. We were not built to endure horrendous cold. But there are a few organisms who are built to live, or if I may say, die and then live again in extremely cold temperatures.

Meet the Wood Frog

Wood frog, a small variety of frog found in north america is one such creature. You ask what’s so interesting about them?

It is probably one of the most freeze tolerant beings. In other words, extracellular freeze tolerance and intracellular freeze avoidance enables the frog to do what it does.

Well, when it is really cold out there in the Arctic circle or the upper parts of America, they can freeze themselves for weeks, even for months. It does this by first finding out if it is really cold out there. When it touches the first bits of winter snow, a signal sets off in its body and the signal starts the blood freeing process.

All the water is pulled away from the core of its organs and the water gets frozen. Putting all the organs in a shell of solid ice. The whole frog becomes hard as a rock and sits there like that for weeks. Till it sees the spring time.

The most amazing part is that, during this time, the frog doesn’t breathe, its heart stops beating and even kidneys stop functioning. In medical terms it could be called dead. In reality, it is only temporarily dead.

Just like a dead man – without a hear beat – walking.

And then spring comes. It thaws itself out without any cellular injury and starts jumping again. It dies in winter and comes back to life in the next season.

This is probably how carbonite from Star Wars works.

The Ultimate Roller Coaster Ends Lives

By Anupum Pant

Euthanasia Coaster, A concept designed by Julijonas Urbonas, is a one of its kind roller coaster concept designed to literally kill you. As the name suggests, it is an engineering marvel designed to intentionally end lives of people suffering from terminal illnesses or the ones who are bored of a too long life – a practice referred to as Euthanasia. The coaster is a different kind of Euthanasia machine.

The concept, according to him is a humane way of ending lives of people who don’t want to live any more. Since, Euthanasia is seen as a suicide by some, it has been banned in some countries, while there are others who consider it legal. Similarly, the humane way of ending life by inflicting euphoria and thrill is considered a marvellous concept by some, and there are also others who are extremely disgusted by the idea. Most find it morbid.

Since Julijonas neither encourages nor discourages suicide, I think it isn’t right to judge him by his concept.

It kills you by extreme G forces that are produced at certain parts of the coaster. In simple words, it kills you by depriving your brain of oxygen. The medical term for it is Hypoxia. It does this by taking you up half a kilometre high and then dropping you into a 10 second long fall. It is built to carry 24 people and it ensures that all of them come back dead.

There is no organization who plans to build it yet.

A tip you don’t need: Another way to die out of pleasure would be to feed yourself Theobromine. Now where would you find it?

Dark chocolates! A tiny bite of dark chocolate can easily kill your dog. But, if you are an 80 kg human, you need to consume about 10 kg of dark chocolate to kill yourself. That would be a great way to go, wouldn’t it?

Watch How 32 Metronomes get Synchronized Automatically!

By Anupum Pant

Background

From biological cells to celestial bodies spontaneous synchronisation is found everywhere in the nature. In simple words, you could call “spontaneous synchronisation” as “a natural self-organisational behaviour” in things. Where, out of a chaos, uniform order starts appearing. If that feels too abstract to understand, read on…

Probably the first human to note this effect was a Dutch physicist, Huygens. Huygens noticed this when he was working on a ship with two pendulum clocks. For very long times, his work of calculating longitudes required him to watch these clocks swinging away their pendulums. He would lie on the bed and watch them go. There was one weird thing he noticed about these pendulum clocks. No matter how the pendulums started swinging, after an hour or so, both the pendulums ended up synchronized! This was a perfect example of uniform order appearing out of no where from an apparent chaos.

The effect amazed scientists for about 350 years. Only then some researchers at Georgia Tech University, were they able to produce a perfect mathematical model that proved it. So, what was happening on the boat? In a similar fashion, would all pendulum clocks in the world get spontaneously synchronized? Let’s look at the following example to find the answer.

Synchronizing metronomes

Think of it this way. You have a couple of metronomes with you – the physical ones, the ones that are based on pendulums. You start each one of them and there is almost no chance that you’d get them perfectly synchronized in the first go. So what do you do to get them synced?

You simply keep all of these metronomes (ticking with the same frequency but different phase relations) on a free-floating table. That gets them synchronized in a matter of minutes. See how the 32 metronomes completely out of sync of each other get synchronized in the following video. Note that they are on a surface that is free-floating.

Adam Milkovich explains the effect very beautifully in the following video:

Back to Huygens

Now, if we come to see the boat as a free-floating base and the 2 discordant pendulum clocks as metronomes, the segue of their motion into a perfectly synchronized one, makes complete sense.

The only difference is that the boat was a pretty huge free-floating base – something which has a relatively very high mass as compared to the pendulums. And then there is the drag on water; other forces etc.. The pendulums had a very very tiny effect on the boat and in turn, were able to transfer only a teeny bit of energy with every oscillation. So it took longer.

I find it pretty incredible that it even happened in an hour. I think it would have taken a much longer time, given the huge difference in their masses. May be Huygens exaggerated. Or it was a very small boat. Anyway, that is the reason, Huygens’ clocks took about an hour to get synchronized. While the ones we see above are able to do it in a matter of minutes.

Back to the Question

Would all pendulum clocks in the world would get spontaneously synchronized?

Well, I’m not too sure. But this is how I see it:

I think of Earth as a really really really huge free-floating boat. Now, the movement of pendulums on Earth certainly has an effect on the earth. And in turn the other pendulums get affected. And they end up synchronized at some point. But the first effect itself is unimaginably small.

I mean, the Earth is so massive that even if all of the 7 billion people on Earth jumped at the same time, the 6-trillion-trillion-kilogram Earth would move so less. Earth would move about a hundredth of the radius of a single hydrogen atom.

So, pendulums would hardly have any effect. But the effect would certainly be there.

Therefore, I’d say the answer is yes. Yes, all the pendulum clocks on earth would eventually get synchronized. But it would probably take so long, that even earth, leave alone pendulum clocks, would cease existing.

Toy idea: Well, that gives me a great idea for a toy. 5 – 10 pendulums inside a huge pendulum. The inner ones would get beautifully synchronized automatically!
