The Largest Object in the Solar System

By Anupum Pant

On November 6th 1892, after being spotted by a British astronomer Edwin Holmes, comet Holmes was not seen again for several decades. Thus it came to be known as the lost comet. Out of the blue, more than 70 years later, the comet was again seen in the year 1964.

Now it is known that comet Holmes was captured by Jupiter several thousand years ago, and it never went back to the Kuiper belt. It is a Jupiter family comet. Every 6.88 years, the comet orbits the sun.

Even this year, on 27th of March, it was one of the most bright comets of the year. But it was something that happened back in the year 2007 which made it one of the most popular comets in the sky.

For a brief period, comet Holmes, which is also a part of our solar system, became the largest object in the solar system. Yes, even larger than the sun!

On November 9th 2007, the diameter of comet’s coma – a cloudy region surrounding the comet made up of very tiny shiny ice and dust particles – measured about 1.4 million km. The sun’s diameter rounded to the nearest hundred is estimated to be 1.392 million km. Agreed the coma wasn’t as massive as the sun, but the size of it did measure slightly more than the sun at that time.

It indeed is a great achievement to become the largest object in the solar system (for some time) for an object that is just a tiny mass of ice and dust that is only about 3.6 km wide.

That day, the cloud around it erupted due to a mysterious outburst which still puzzles scientists. Such outbursts have been seen in the past too and are thought to have been originated as a result of its collision with a meteor (or probably due to an internal steam eruption).

A Piece of Paper as Thick as the Universe

By Anupum Pant

Linear growth is only what we can visualize well. Estimating things that grow exponentially, is something not many of us can do properly.

Here’s what happens when you fold a piece of paper. A paper of thickness 1/10 of a millimetre doubles its thickness. On the second fold it is 4 times the initial thickness and so on. It doesn’t really seem like it would grow a lot after, say, 10 folds, right?

After 10 folds, the paper which was about the thickness of your hair, turns into something that is as thick as your hand.

Without any calculation, how thick do you think would it become if you could fold it 103 times?  (I know, no one has ever folded a paper more than 12 times)

Think about this for a second: How many times do you think would you have to fold a paper to make it 1 kilometre thick? The answer is 23. Yes, it takes just 13 more folds to go from the thickness of a hand to a whole kilometre.

Turns out, if you manage to somehow fold a paper 30 times, it would become 100 km tall. The paper would now reach the space.

For the sake of imagining how exponential growth works, a paper folded 103 times would be about 93 Billion light years thick – which is also the estimated size of the observable universe.

Watch the video below to see one other great example of how exponential growth can mess with you.

Note: In the past, I’ve been requested by my readers to keep the articles on AweSci short. It made sense. Since I write one article everyday, for readers, it definitely is easier to read and digest a smaller article, day in and day out. Thanks to the rate at which short attention span is being nurtured by the internet, not all have the appetite to take in bigger pieces everyday.

I see it this way – doing a very little thing everyday religiously, compounds. It makes a huge difference in your life. Even devoting 2 minutes a day for a single thing makes big changes over time. Here, I’m doing more than an hour everyday! If you read these daily, you are devoting around 10 minutes a day to learn something. You’ll do great in life!

At the same time, smaller articles of about 300-500 words are good for me too. By sticking to smaller ones, I can accomplish my own goal of learning and writing about one new thing everyday, by doing less. Also, composing smaller articles doesn’t take a lot of time which allows me to take care of the primary daily activities.

However, today, a reader asked me about the decreasing length of my articles. It’s so good to know that readers actually care about these things. Nevertheless, as explained above, there’s nothing wrong in it, but it did make me think about what was causing it? Well, I’ve been busy with so much stuff for the past few days, I don’t have partners for the blog and it’s tough doing it alone. Still, with all the travelling and full day outings in a 40 degree sun for the past few days, I managed at least one article a day. Pat on the back to me for being able to do that.

Anyway, the point is that articles don’t have to be long. For the question my faithful reader asked me, I needed to write this to explain it to him. He deserves a good explanation for being faithful reader to my little blog. If I learn something and sleep a little bit smarter than the last day, I’ve accomplished my goal for the day. That way, the purpose of you reading this is served. That way, the purpose of the blog is served.

What do you say, long or short? Or, you are always welcome if you want to contribute on this blog. We have hundreds of people who’d come by daily to read your article!

Background

In the past, we’ve seen how geniuses at MIT have figured out a way to capture the beam of light on video, and have replayed it moving in slow motion. In simple words, moving light was captured on camera. Something which the human eye had never seen before was shown moving with the help of technique. But, then there are other invisible things too. Like sound!

Watching sound

Watching the iTunes visualization go, isn’t equivalent to watching sound. Visualizations and waveforms are merely a digital depictions of sound.

While listening to sounds can be too easy, seeing it with your eyes isn’t natural. For that, there is camera trick that can be used to see the actual sound waves travelling in the air. In fact, with this technique, any disturbance in the air can be seen which otherwise, would be totally invisible to the naked eye. It let’s you see sound!

The camera technique has a fairly confusing name. It’s called Schlieren flow visualization. But that shouldn’t confuse you because in simple words, with this technique it is possible to capture on film, the disturbances that are caused by things moving in the air. For example, the invisible disturbances that are caused in the air (a transparent medium) when someone claps can be made visible by using the technique – Schlieren flow visualization.

Here is how it works

If I write it in words, I’ll only confuse you more. So, here is an NPR video that explains the mechanism very accurately. Otherwise, there’s always this NASA page for it.

Amazingly, like the video shows, it can be used to see the heat coming off the human body. Now, I can definitely think of some creative applications for that.

Titin Protein – The Longest Word in English

By Anupum Pant

Background

No, I’m not talking about the fictional character Tintin. It’s Titin I’m talking about. The initial part of it is pronounced almost like Titan, but please do not confuse it with Titan.  Titin is the largest protein molecule ever discovered. Soon you’ll see why it is the largest…

Titin is the short name for an extremely massive protein molecule. The full-length scientific name of this protein molecule contains 189,819 characters and is considered (by some) as the longest word in not just English, but any language.

Others choose to not consider it a word at all. You won’t even find the full scientific name of Titin in any dictionary. According to lexicographers it is only a chemical formula, not a word. Technically, they are right. So, it is not really the longest word in English.

In that case, probably a lung disease called pneumonoultramicroscopicsilicovolcanoconiosis can be considered the largest word. There are 45 letters in it. But my history teacher once told me that floccinaucinihilipilification (meaning, the estimation of something as worthless) was the longest word in English. Well, someone needs to tell me which one it really is. Till then, I’ll consider Titin as the undefeated champion…

What is it?

Titin is a protein found in certain kind of muscle tissues. It is the thing that makes those muscles elastic. For instance, in heart muscles – that expand and contract continuously for decades, without a break. The folded nature of this huge molecule makes it act like a spring – just like a long wire can be coiled into a small spring. The full chemical formula goes like this:

C132983H211861N36149O40883S693

I won’t spam my blog with the full name, but I’ll definitely point you to it. [Full name spelled out]. If you are too lazy to go there, it starts like this:

Methionylthreonylthreonylglutaminylalrylglycylphenylalanylprolylvalylprolyylglycylarginylalanyllysylleucylthreonylglutamylleucylleu…

and ends like this:

partylaspartylleucylthreonylthrnylaspartylvalylglutaminyllysylglutamilthreonylleucylserylleucylglycylasparalaspartylserylalanylthr…

The video: It takes about 233 minutes to pronounce the full chemical name – Yes, a guy tried it out (with video cuts of course). The gentleman pronounces it on camera for you. If you care enough to watch the whole 3 and half hour-long video, you’ll see how the man grows a stubble while pronouncing it. Also, you’ll see the plant dying out. But those are only gimmicks that makes the video funny. I’d like to add that his expression in the end is priceless. You shouldn’t miss that. Here, I’ve attached it for you below:

To use up the same amount of time in a better manner, I suggest that you watch the Bill Nye vs. Ken Ham debate.

His Blood was a Powerful Snakebite Serum

By Anupum Pant

Background

Trust me, this isn’t an April Fool’s joke. Bill Haast, born in the year 1910 was one very interesting person. He was a man who was immune to the bites of some of the world’s most dangerous snakes like cobras, vipers (and others). He was the only person to have survived 3 king cobra bites. He even survived the bite from a blue krait (the snake died). Not just that. His blood was treated as a powerful snakebite serum. He also saved countless lives simply donating his blood. Was it a superpower of some sort?

Did you know? Venom and Poison are not the same things.

How?

Maybe you could call it that. But, the superpower did not happen spontaneously. He did it to himself. He turned himself into a human experiment (at the cost of his life) to attain this level of resistance to snake venom.

His secret: Bill Hast, bitten by snakes more than 170 times, in his time, was a man who was bitten by poisonous snakes more times than any other living man. But those were mostly accidents that happened when he handled snakes during his career with snakes, a career that lasted more than 60 years. He built antibodies in his blood by voluntarily injecting snake venom every week since 1948! When he started doing this to himself, he did not know if he’d survive.

However, the man went on to hit 100 years of healthy life. Look at how he moves around at the age of 88. (Certainly not as agile as the 86-year-old gymnast – the super grandma. No one beats that!). He died on June 15, 2010.

His job: His real occupation was to collect venom to make anti-venom serums. He owned about 10,000 snakes. He collected the venom by repeating the process thousands of time (at the same time he was kind to the snakes). For drug companies in the year 1990, he was the source for 36,000 samples of venom.

Did you know? There is a Wasp that turns a cockroach into a zombie with its venom!

The other side of it

Of course the superpower came with a cost. In the video, you can see how had gnarled, he had lost the use of couple of muscles in his hand and had scars all over. He did it all with good intentions in mind, not for the money. Bill Haast, certainly was a legend.

Moving Light Captured on Camera

By Anupum Pant

The speed of light

In vacuüm, light travels 299,792,458 meters in a single second. In other words, in a single second it travels 186,000 miles. To establish a  perspective, if I could move that fast, I would circumnavigate the world in 0.13 seconds. A hypothetical jet plane would take more than 2 days to do the same. In short, it is fast. It is the fastest – Nothing beats light.

If you try to record moving light on a home camera, you’d fail miserably. That is because normally they can roll only about 30 to 60 frames per second. In fact, you’d not even be able to capture a fast-moving ball without motion blur, forget recording moving light. To record fast things you need fast cameras that can roll several thousands of frames every second.

In the past, high-speed-cameras, rolling film at thousands of frames per second have been able to record bullets moving in slow motion, bubbles bursting, people getting punched and what not! MythBusters use such cameras for almost every experiment they do.

But light travels a million times faster than bullets. Till the year 2011, to capture moving light on film was considered an impossible feat; and then, a team from MIT media lab invented this.

A 1,000,000,000,000 FPS camera

A camera that can record at a speed equivalent to a theoretical one-trillion-FPS camera was invented by a team at MIT media labs in the year 2011. This camera can record light moving through space, in slow motion! To look at what it can do, you’ll have to watch the video below. In the video, the researcher explains its mechanism in detail.

It is theoretically impossible to craft a mechanical device that can roll film at such extremely high speeds. To tackle this physical limit, these geniuses invented a whole setup containing several cameras sensors that work together to make this feat possible.

Note: In reality, the camera doesn’t record the footage of a trillionth of a second. It is a composite video of lines of different pulses of a laser recorded and stitched together. The time it takes to compile enough data for the video, is more than what it takes the light to travel from one end to another.

Ming – A 507 Year Old Organism Killed By Scientists

By Anupum Pant

A few years before Leonardo da Vinci started painting the Mona Lisa, somewhere deep in the ocean, in the year 1499, a clam was born. When it stepped into this world, it was also the period of Ming Dynasty in China, so several years later the clam was named ‘Ming’ (Scientific name: Arctica islandica) by scientists. Ming was the 507 year old organism that unfortunately got killed.

Like crocodiles, clams are also one of those biologically immortal organisms. This one lived on for 507 years till the year 2006, when it was discovered by a group of researchers in deep oceans. Unaware of its age, researchers stored it like all the other 200 clams they had gathered, using refrigeration, which killed it (and the others). It was an unfortunate accident; definitely not intended in any way.

World record: Ming the clam was recorded as the oldest individual animal ever discovered. The record mentions “Individual” because often colonies are recorded to live for really long times. By those measures, this clam would have stood nowhere in comparison. For example the deep-sea black and gold corals 2700 years old have been found. But, scientists are pretty sure that there are older individual organisms [than Ming] still living out there, waiting to be discovered.

Why do they live so long?

Their genes, extremely slow oxygen intake and very slow metabolism are some of the known factors that enable these clams to live for centuries. Their age is measured accurately by using Radiocarbon dating.

The Rings: But more importantly these clams have rings on their shells. These rings are like our fingerprints, unique for each clam. The number of rings on the shell also gives a pretty accurate estimate of their ages; like rings on a tree stump help us to find the age of a tree. Initially, a few researchers, using these rings, wrongly estimated the age of Ming to be around 400 years. It was corrected later by others.

The oxygen isotopes present on the rings can be detected too. These measurements give scientists a useful insight about the climate changes that must have happened over the years.
