Horrible Rare Genetic Disease Turns Humans to Statues

By Anupum Pant

Background

At an early age, the horrible, rare and poorly understood disease that we’ll discuss today – FOP – starts producing tumours in the body. Doctors usually assume it to be the fairly common cancerous tissue but when it turns out to be FOP, everybody panics. Yes, this one is more ruthless than cancer. How?

Well, FOP (Fibrodysplasia ossificans progressiva) turns humans into statues. It is also known as the stone man syndrome. It is an extremely rare genetic disorder in which the muscles and other connective tissues in the human body start turning into bone. Some times it happens automatically, other times it happens when the tissues are damaged. Gradually, the patients who are affected by FOP are imprisoned in their own skeletal prison.

FOP is one of the most bizarre diseases. And has no solid cure.

Why does it happen?

It happens because of a gene that fails to turn off. This gene is responsible to form bones in a baby’s body when it is still in the womb. Once the job is done, the job of the gene is to turn off itself. But when this deactivation of the gene doesn’t happen, the gene keeps making bones even after the child is born and ultimately turns a human into a statue made of bone.

Ashley Kurpiel: When Ashley was just 3 years old. Tumours started appearing in her arm. Doctors thought they were cancerous tissues and started taking steps to deal with it. Only when they removed her arm, the doctors realized it wasn’t cancer, it was a horror. They found, she had FOP. She was slowly turning into a statue made of bone.

Harry Eastlack: When he was 5, he broke a leg and then there were other complications while the fracture was being treated. The fracture didn’t set correctly. This made his hip and knee stiff and bone growths started on the muscles of his thigh. The transformation of muscle/tendons to bone started happening in other parts of the body too. By the time he turned 20, his backbone had turned into a single stiff piece of bone. When he was 39 years old and was almost turning 40, his body had turned completely into bone. His jaws were locked and the only part he could move in his body was his lips. Harry died from pneumonia before he could turn 40.

This Disgusting Child Abuse Mental Disorder is Real

By Anupum Pant

Background

If you’ve paid enough attention to House MD, then you probably know about this really interesting mental disorder called the Munchausen syndrome. If you don’t, well, let me give you a crash course on Munchausen and the plot of that episode of House MD which deals with this disorder. But remember, this article isn’t just about Munchausen syndrome. If you think Munchausen is interesting, you’ll be amazed to read about what this article gradually  moves on to discuss – a much more interesting (or better call it disgusting) disorder that is closely related to it – The child abuse mental disorder.

Season 2 Episode 9 of House MD and the Syndrome

From IMDB: At a betting parlor where House happens to be, a woman collapses and House makes sure she gets to the hospital. He thinks she has Cushing’s syndrome while Cameron starts to think she has Munchausen syndrome.

Munchausen syndrome: It is a mental disorder in which the patient fakes an illness to draw attention. Some other times, they just do it to gain sympathy or to get admitted to hospitals. This is the reason it is also called a hospital addiction syndrome or hospital hopper syndrome.

To fake illnesses these patients go to the extent of consuming harmful substances, or some times they go as far as, studying in detail the medical details of an illness, to produce certain symptoms that would confuse doctors and would result in their long vacation at hospital. They sometimes do it consciously, other times they don’t even realize that they are doing it to themselves.

Munchausen is completely different from the silly fabrications or exaggerations of symptoms that children or adults make to get access to financial compensation, absence from work, or access to drugs. It is a mental illness.

Sometimes this problem can go deeper and worse.

Munchausen syndrome by proxy

In this, the person does not use himself/herself to gain attention or sympathy. They use a proxy. Most times, parents go as far as inducing symptoms of a disease in their child. This variant of Munchausen is indeed considered as child abuse.

If a mother is affected by a mental illness like this one, she would for instance, drug her kid in a way that he/she starts throwing up, or starts having some other symptom. They might also resort to other evil or dangerous tricks that would make their child appear sick.

Once the child gets admitted at the hospital, such parents often try deceiving the hospital staff by being helpful or faking great devotion or self-sacrifice towards their kid at the hospital. In such cases it gets really tough for the doctors to suspect the diagnosis of Munchausen syndrome by proxy.

Being close to the child at hospital helps the “actual patient” – the one with the mental illness – in two ways. One, by gaining the sympathy of the hospital staff. Other, by getting access to the kid to induce further symptoms in order to make the illness last longer. As a result, they get attention and sympathy of others for a longer time.

Think about it. A mentally ill parent harming their own child and inducing them with life-threatening diseases just to gain attention. How disgusting is that!

The Astonishingly Funny Story of Mr. McArthur Wheeler

By Anupum Pant

In a wonderful paper titled “Unskilled and Unaware of it“, two social psychologists from Cornell University, Justin Kruger and David Dunning share an incredibly funny story of Mr. McArthur Wheeler. Although it is funny, the story actually beautifully demonstrates an excellent concept – a kind of cognitive bias (discussed later in the post). Here is the story:

The Story of Mr. McArthur Wheeler

On one fine morning in Pittsburgh (PA), in the year 1995, a man aged 44, known by the name McArthur Wheeler decided to rob a bank. Since he thought he knew a lot about a peculiar chemical property of lemon juice, he decided to smear the juice on his face before executing his plan to rob the bank.
His logic – As lemon juice can be used to write invisible letters that become visible only when the letter is held close to a heat source, he thought, the same thing would work on his face too. By smearing lemon juice all over his face, he thought that his face would become invisible to the security cameras at the bank. He did not just think that, he was pretty confident about this. He even checked his “trick” by taking a selfie with a polaroid camera. I’m not sure if the film was defective, or the camera wasn’t operated properly, but the camera did give him a blank image. The blank image made him absolutely sure that this trick would work. Or he would not have ever dared to rob a bank with lemon juice on his face.

That day, he went on and robbed not one, but two saving banks in Pittsburgh. A few hours after he had done his job, the police got their hands on the surveillance tape and decided to play it on the 11 O’Clock news. An hour later, an informant identified McArthur in the news video and contacted the police with the man’s name. McArthur got arrested on the same day. Ironically, the same surveillance cameras that he was confident would not be able to capture his face, got him behind the bars. During his interaction with the police, he was incredulous on how his ignorance had failed him.

The Dunning and Kruger effect

Both the psychologists Dunning and Kruger got story of Mr. McArthur. They decided to study it more deeply. The psychologists were interested to study about the utter confidence of Wheeler that made him believe he’d be able to foil the security cameras with lemon juice on his face. He had the confidence, but he clearly wasn’t competent enough…Why was he so sure he’d succeed?

Their study finally demonstrated that the less competent an individual is at a specific task, the more likely they are to inflate their self-appraised competence in relationship to that task. This phenomenon is today known as the Dunning–Kruger effect.

As Charles Darwin rightly said:

Ignorance more frequently begets confidence than does knowledge.

Dunning Kruger effect McArthur Wheeler
At zero experience in the x axis it’s not “no nothing”. It’s *Know nothing (There’s a spelling mistake in the image) – ‘On Finch’ mentioned this in comments below.

Indian Idol contestants and the Dunning Kruger Effect

This effect is clearly observed during the auditions of reality shows like Indian idol (etc). The auditions are usually thronged by a variety of good and bad singers. The ones who are bad at it, never realize their incompetence and yet are genuinely disappointed when they get rejected. Often times, they resort to noisy quarrels too.

If you’ve observed carefully, people who aren’t very good at humour or sarcasm often tell poor jokes and expect people around them to laugh hard. But when people don’t laugh, they seem genuinely shocked. It is incredible to see them totally unaware of how bad they are at it.

At every place, it is a common tendency of the least skilled people to have an inflated sense of self-competency.

Ignorance sure is a dangerous thing.

Flynn Effect – IQ Test Scores say We Are Getting Smarter Every Year

By Anupum Pant

My Opinion of the IQ tests

I don’t like IQ tests (WAIS, WISC, etc). Why?

Well, IQ tests are designed with an assumed definition of the word “intelligence”. They assume that “intelligence” can be estimated by measuring how closely a person thinks like the other “intelligent” people (probably the ones who design the test). IQ tests measure general Intelligence, not “intelligence”. However, today general intelligence and intelligence are used interchangeably by most of us.

IQ tests are standardised tests that give you standardized test scores which merely indicate how well you would perform at other standardized tests (academic performance). Also, these tests are not an indicator of how well a person would do in his/her life.

IQ tests assume that General intelligence and Intelligence are the same things, or this is what the society has come to believe. To them, the other sub-intelligence types like interpersonal intelligence, intra-personal intelligence, musical intelligence, creativity, memory etc. mean nothing.

I think, intelligence is a much more complex quality than what IQ tests assume it to be. Quantifying intelligence is hard and presently no test does it properly; probably no test ever will…

For instance, the Megasavant, Kim Peek (Rainman) scored a below average (87 points) on general IQ tests. Agreed, he couldn’t button up his shirt, but he could speed read a book in about an hour and remember almost everything he had read. Besides, he could accurately recall the contents of at least 12,000 books which he had read in his life. And yet, this incredible ability meant nothing to the IQ tests. IQ tests looked at him as a guy with just a below-average IQ.

However, I’m not here to debate on IQ tests today. Let’s take it to the comments section. Tell me what do you think about these tests.

I like it or not, I can’t deny the fact that it is a world standard. And there is definitely a solid reason for that. So let’s just learn something about these tests…

The Flynn effect

Did you know, the IQ test scores are not absolute. The score you get is adjusted in a way that keeps the average IQ at 100 and also ensures that 2/3 people lie in an IQ band of 85-115 points.

But that is what IQ tests and scores are based on, so many people probably know that. There is one other thing you almost certainly did not know…

The WISC test: One of the widely used IQ test is called WISC (Wechsler Intelligence Scale for Children). It started in the year 1947, and to ensure that the average IQ remains 100, it has been recalibrated 3 times in the 70s, 80s and the 2000s decade. Today WISC IV is used.

Had our grandparents taken the present WISC IV test about a century back, they would have probably scored 70 points on an average. That would have classified them as mentally retarded! Clearly, we have become smarter. Or what?

Yes, in fact the constant increase in this average IQ test scores has been observed for a long time by scientists. They have measured a gradual rise of 3 points every decade and this effect is called Flynn effect. And that is the reason the test has to be recalibrated regularly – to keep the average at 100 points. Is this evolution doing its work?

Why does it happen

Frankly, no one knows for sure. Like the theories that offer explanation on what sleep exactly does to our brains, even Flynn effect has a couple of possible explanations. Three of the most plausible ones are these:

  1. “Better” schooling or in other words better training  at schools which makes students get familiar with the IQ test pattern, is one explanation. Our schools have evolved to impart education in a form that helps a kid do better at IQ tests. This is pretty clear from the way our present education system doesn’t give much importance to creativity, just like IQ tests don’t…although it beats me, why memory is given a substantial weight-age at schools.
  2. Improved nutrition is another explanation. Most certainly, excluding fast foods and other such foods, we eat better things than what our grand-parents used to. The inclusion of iodine in common salt is one such example. Also, parents these days ensure that the children in their formative years get the best nutrition – exactly at the time when the brain forms most connections. That could have clearly helped us get smarter.
  3. Some researchers have a different take on how better education and nutrition has helped us get smarter. They suggest that the better lifestyle, education and nutrition has had an effect on our IQs by reducing the intensity of infectious diseases.

What do you think? Do you agree with the IQ test system. Do you think it isn’t just a social phenomena? What else could be the reason that we are getting smarter? Tell me in the comments.

Talk by Arvind Gupta Will Make You Salute Him

By Anupum Pant

Background

We are all born scientists. Young kids have an inborn talent of thinking and learning by interacting with their environment – just like scientists do. Their everyday play is a type of experimentation and the toys they use, are their scientific equipment.

But unlike the children of developed countries, in India, a major chunk of little kids are not fortunate enough to cross ways with these fancy toys. In a place like India where 70% of the nation’s population still resides in backward villages, a man like Arvind Gupta is doing some really incredible work that deserves a salute. He’s popularizing science among kids by showing them quirky ways to convert trash into useful toys.

The Story of Mr. Gupta

He is the Indian Bill Nye – the Indian science guy – Arvind Gupta.
Arvind Gupta calls himself a toy maker (I think that is a very humble name he gives himself) and he has been doing it for the last 30 years! During the 70s when Mr Gupta was studying in IIT – Kanpur, he lived through a period which came with a revolution that aimed at revitalizing primary science in the village schools. Later, he went to the US, studied at Caltech, came back, worked at the top research laboratories in the country, and yet he wasn’t satisfied.

He somehow felt that the cutting-edge research he was doing, its effect on the major part of the Indian people wasn’t directly visible to him. This was when he started a village sized program to popularize science among the rural kids. He continues to do this even today. His way of doing it – Teach them to convert trash into toys. It was a beautiful idea.

I still remember watching Arvind Gupta on Doordarshan, teaching us science. We never noticed we were learning –  by touching, feeling, cutting, sticking – pulling things apart and putting things together.

His toys

He can turn anything into a toy that explains a basic science principle in a very interesting way to children. For instance, his way of sticking match sticks together to make objects as simple as 2 dimensional angles to objects as complex as bucky balls, is just amazing. But that’s not all.

Go to his YouTube channel you’ll find a number of tutorials to create amazing little devices from trash, which even adults will enjoy. Besides that, to cater to the linguistically diverse population of India, his videos come in languages like Hindi, English, Tamil, Bengali etc…

Watch his talk below. In a 15 minute breathless talk you’ll watch him demonstrate everything from simple mathematical, biological, chemical and physical principles with match sticks and rubber tube parts, to at least twenty other plain yet ingenious toys. Watch him make it all, right there at the talk! You can’t miss it.

The one I like the best is the slate he makes, using wool and velcro, for blind people. The second best toy in my opinion is the incredibly simple whistle made by cutting a straw. The crank generator made of trash is impressive too! What do you like to most? Let’s discuss in the comments below.

Every kid would love science this way.

Five Mundane Things That Can Be Turned Into Diamonds

By Anupum Pant

Background

Diamonds are natural things…or are they?
All of those who have bought a wedding ring, have most probably been informed at the shop that diamonds can be made in the laboratory. And these diamonds are virtually indistinguishable from the real (mined) ones. Today they go by the name, laboratory-created, lab-grown, synthetic diamonds or man-made diamonds and are available at almost all jewelers. They have the same physical and chemical make up as that of the mined diamonds. The primary difference between the real deal and the lab diamond is their price. The lab-grown ones are usually easier on your wallet.

Normally, synthetic diamonds can be made using 2 different processes – high temperature and high pressure method and Vapor deposition method. The former is used to convert most mundane things into diamonds. But the later is used too…

Note: If this post reminds you of the classic track, Diamonds made from rain by Eric Clapton, then for a minute, you might want to stop playing it in the back of your head. And for the record, no, diamonds cannot be made from rain.
Fun fact: However, scientists say it does rain diamonds right here, in our own solar system, in the planets Jupiter and Saturn. But that is for some other day.

For now, I have collected a small and interesting list for you below. Four out of 5 are made using a similar process (number one from the two mentioned above). The list has been made to realize how there are diamonds hidden and lying around you. Let’s see what are those mundane things that can be turned into diamonds, right here on earth, in laboratories.

Disposable Paper Microscope Costs Just 50 Cents

By Anupum Pant

Background

While doing my daily rounds on the internet today, I came across this awesome piece of modern engineering – An extremely durable and disposable microscope made out of paper and very tiny ball lenses. I saw it first on a Ted talk that I’ve attached below. Ingenious I say!

What’s new?

Microscopes are no longer those sensitive, bulky and costly instruments which were used to observe tiny life forms. These engineers have changed the age-old definition of the microscope. The fold-able paper microscope or foldscope is an origami microscope that weighs just 9 grams and is designed by a Manu Prakash, a Bioengineer professor and his team from Stanford. Instead of costing thousands of dollars, this ingenious origami microscope costs less than a dollar and is set to transform the way people use microscopes.

Besides being light, cheap and foldable, the microscope is water proof, durable to the extent that it can be dropped from the top of a building without getting damaged, does not require any external power, provides a 2000x magnification, can be assembled by a first grader in ten minutes, is easy to carry and is absolutely flat! What more can we ask for!

It can even project the image of bacteria on your wall. How cool is that! I bet your lab microscopes can’t do that.

It is set to transform the lives of those billions of people living in the developing countries. The piece of engineered paper will change the speed and accessibility of medical diagnosis in the poor nations.

Material and actual cost

Well, as the heading tells you it is a 50 cent microscope, not really. It costs only a little more than that. Still, it costs lesser than a dollar – about $0.97. Here is the material cost break-up:

  • Tiny Spherical lens: $0.56
  • 3V button battery: $0.06
  • LED light: $0.21
  • and a couple of other things like tape, paper and switch: $0.14
  • Total: $0.97

Beta testing: The team is currently looking for beta-testers for Foldscope. They’ll choose 10,000 people who would test it in a variety of settings and would help them generate an open source biology/microscopy field manual. See “Ten Thousand Microscopes signup” for details.

It reminds me of

The incredible cheap microscope discussed above is new and very precise. Until recently we didn’t have that. DIYs on the internet taught us to construct (not really) not-so-accurate microscope setups at home using a laser pointer.

All you were supposed to do is point the laser pointer through a suspended drop of bacteria infested water (or other clear liquids).This is how I toyed around (I still do) with a laser pointer to see hazy pictures of possible micro-organisms:

Problem with Facebook – On Facebook Everybody Loses

By Anupum Pant

I had to say this a couple of weeks back. But, now I think, I’ve gravely been irritated by Facebook to let it out. So here goes a post on how Facebook is repeatedly trying to make you confirm your own  pre-conceived notions and is basically making you an ignorant person everyday, is hurting page owners, and they are doing all of this to make short-term money for themselves. It is evil. That, is the problem with Facebook.

Almost every good thing you want to see is hidden from you on Facebook

Okay, let us start with my Facebook page. I know it is a small one, with just 446 likes (as of today). That said, I can tell you one thing for sure, I never forced any one of these people to like my page, nor have I ever advertised my page on Facebook to amass likes. All, or may be most of the people who like my page wished to clearly subscribe to my content and my views. Clearly, they wanted to be updated on the things I was posting. But Facebook tells me, that isn’t happening, unless I pay them the money.

Now take a minute to look at the screenshot below:

Facebook page insights
Look at the total reach.

See the first post in that list. Of all the 446 people who’ve subscribed to the page, this appeared on only 15 news feeds. Moreover, the chances are high that all of these 15 people must have not even scrolled down to see the loaded post. So, probably 10 of the 15 loads were just useless loads. 5 of them who actually saw the post, decided (probably subconsciously) to not engage – that is understandable. Even if all the 15 people did see this post, how is that fair? Continue reading Problem with Facebook – On Facebook Everybody Loses

Chocoholics Have no Fear, Chocolate Pudding Fruit is Here

By Anupum Pant

I’ve heard of all sorts of fruits. But this is something I came across just yesterday and I think it is worth mentioning. I bet you haven’t heard of it too. This fruit is called the Black Sapote (the scientific name is Diospyros digyna, in case you need it) also known as the Chocolate pudding fruit or Black persimmon.

Description: The chocolate pudding fruit or Black sapote (not related to the more common mamey sapote) is an apple sized, olive-green colored fruit found in eastern Mexico and Central America. When ripe, it turns from bright green to a lighter shade of green. At this stage it is plucked and allowed to soften for 3-6 days. After it is allowed to soften, the skin turns brownish and the fruit becomes very soft. Now, when it is cut, a smooth and silky textured brown colored chocolate like pulp is obtained from the inside.

Although Black Sapote is slightly larger, It looks a lot similar to the apple like fruit that grows in the world’s most dangerous tree.

Taste and Recipes: Not that I’ve eaten it. Still it is interesting to know that the fruit might or might not have seeds, is delicious and tastes very close to chocolate pudding. The texture is free from any gains and feels smooth in the mouth like papaya. It is often used as a substitute for chocolate in milkshakes, ice-creams, smoothies and juices to impart a creamy rich chocolate color and flavour. It is also mixed with orange juice and served with cream. Other times it is mixed with wine, brandy, cinnamon and sugar.

Health and Fitness: For chocolate addicts, this fruit is actually very healthy. Mostly because it does not fatten you – it is low in fat. At the same time the fruit is pretty rich in Vitamin C. One fruit is said to normally contain four times as much as Vitamin C as an Orange! I don’t have to tell you that Oranges are known for their Vitamin C content.

I wonder why it doesn’t grow in India. The climate pretty much suits it! Or do you have it in India too?

Article In a sentence: There exists a fruit that goes by the name of Black Sapote or “chocolate pudding fruit”. It  tastes, looks and feels a lot like chocolate pudding, is actually low in fat and has about four times as much Vitamin C as an Orange. [Video]

Platypus is a Very Strange Animal!

By Anupum Pant

Background

What would you get if you if you crossed a duck, frog & snake? Hint: It is a mammal and lays eggs!
You’d have one of the most weirdest and mysterious animal, the Platypus.

Knuckles the echinda.pngNote: Unlike what is popularly taught in schools, Platypus is not the “only mammal that lays eggs”. Echidna – Knuckles from Sonic the Hedgehog – is the second kind of mammal that lay eggs.

So, Platypus is considered a strange animal because, it secretive and even today, not everything is known about it. It has a beak that looks like a duck’s beak, it’s feet are webbed like that of a frog’s. Besides that, this cute & cuddly looking creature, found in the Eastern part of Australian fresh waters, uses venom like a snake. But there is more:

Some Incredible things about the Platypus

Firstly, it lays eggs and is not a reptile. It is one of those two mammals which lays eggs.

For up to 3 months the male Platypus stores the eggs in its bill.

They swim underwater with their eyes shut and come out mostly at night.

Venom: They have a sharp and hollow thumbnail (spur) in their hind legs that is venomous. The venom is strong enough to kill a dog (doesn’t kill humans, but is extremely painful). This is used only in self defense. And only males are venomous. I never knew they had venom, but since they are from Australia, I had expected that.

Electrolocation: Under water, they detect electrical signals to find insects, store them behind their bill, come up and then eat them. It uses electrolocation – sees using electricity – Like bats use echolocation.

Under their bill are about 40000 sensors arranged in longitudinal strips. These sensors can detect fluctuations in the surrounding electric field. Even something producing a very minor electric fluctuation at a distance – contractions in the muscles – can be detected by the Platypus.

Sharks do the same and this is the reason they attack and damage our internet cables under the sea.

Mechanical sensors:  Besides that 60000 mechanical sensors (push rods) are used to detect movement in the water. Scientists say that the information from the electrical sensors and mechanical sensors is combined by its brain to calculate the prey’s exact location.

No Nipples: The young ones feed on milk from the mother Platypus. This milk doesn’t come from nipples, it comes from modified sweat glands (not unique to platypus) under its body. It has no nipples.

They can eat their own body-weight in under a single day.

They find it hard to stay underwater because they have a natural buoyancy. Yet, they can use other objects to stay under water for a maximum of 10 minutes. Then they have to come up for air.

Babies: The baby Platypus does not have an official name. Some call it puggle (which is not correct). But the accepted word, “Platypup” can be used.

Water vs. Red-Hot Nickel Ball

By Anupum Pant

Let me just not say anything before I make you watch this video today:

In the video, a Nickel ball is heated using a torch and is dropped into a bowl of water. As the hot ball touches water for the first time, it makes a certain “Ping” sound. It enters the water and gets covered in a bubble sort of thing. As it cools and the bubble is lost, that “ping” sound comes back again. The “Ping” repeats several times and is fun to hear a metal ball do that!

So much fun that the good guys on Reddit even made a couple of ringtones out of it. Download the longer one here. And the shorter one for notifications here.

Why does it form a Bubble cover?

This happens because the metal that is dropped into water is extremely hot and makes the water around it vaporize. The vapor formed around the ball acts as an insulator and doesn’t let the water touch the metal ball. This is the same effect that lets dip your hand in molten lead or Liquid Nitrogen without getting harmed by it. The same thing happens when you drop water on a hot pan – it dances.

This effect is called the Leidenfrost effect and I’ve covered it in an article before…

I’m not sure what exactly causes the “Ping” sound. If you know or have any theories, please tell me in the comments below.

CrashCourse in Quenching

Well, if I’d have wished to piss you off with jargon, I’d have said: “You just watched a hot Nickel ball being quenched in water”

Yes, quenching. Quenching is the name for making a hot metal cool very quickly. It is pretty interesting to know why some one would, with great effort, heat a metal, and then choose to drop it in water to cool off!
Cooling a hot piece of metal very quickly makes it extremely hard. So hard, that the same process is used to make the hard edges of swords that don’t get damaged even if they are used to cut metal!

There is so much more I wanted to write about the process, but I feel this isn’t the right place for it. Let me leave it for some other day.

Can a Single Sand Grain Power a Car for 10 km?

By Anupum Pant

I literally binge on YouTube, especially on science videos. Since I’ve been doing it for a long time, I follow a huge number of channels and among them, are some channels that need a special mention. For that, my plan for today was to create a list of five to ten spectacular YouTube science channels that are not popularly known. But while carrying out the research to collect data for this little list, I happened to stumble upon something which needs a post dedicated to it. So, I thought of delaying my original plan of collating a list of those lesser known science channels.

To tell you about the thing I discovered, you need to know this first:

MinutePhysics: You know MinutePhysics right? I mean, who doesn’t know them. If you think you’ve never come across a video of their’s, try going to their channel. There is a high chance you’ll recognize their signature style of simplifying science – through animated videos. With more than 2 Million fans on YouTube, they have a huge following and almost every video of their’s goes viral, to some extent. It was started by Henry Reich and I’m guessing there is definitely a team behind the channel – If some one from MinutePhysics is reading this, like the one I did with Jaan Altosaar from UsefulScience.org, I’d love to do a short chat with you, if you have the time.

MinuteEarth: Now, the same people who created MinutePhysics also upload similar styled videos explaining the planet earth at MinuteEarth. You should check that out too. But that is not all I’m talking today…

MinuteLabs

I’m not sure how I landed on the Youtube page of MinuteLabs.io, but the instant I spotted the dot io in the end, I knew there was more to this channel than just two videos. I watched one of those videos – video (embedded below)

I could instantly connect to what Jasper was doing in the video. I often have such questions and I make these queries on Google all the time. But I had never endeavored to do what he (maybe with his team) did on his website.  And that brought me to MinuteLabs.io‘s Mass-energy scale.

Mass-Energy scale

When you land on the Mass-Energy scale page of MinuteLabs, you’ll find a vertically massive scale, listing out a couple of things on the right and left side. So, this is a scale which is based on the popular equation E=MC2 .

It lists out a number of everyday (plus other) objects and the energy associated with them on the left side. On the right side of this scale are the masses of some other objects. This is how it works…

minutelabs mass energy scale

For example, if you take the mass of a sand-grain and multiply it with the constant C2, you’ll end up with some amount of energy (E) that is *theoretically* stored in its mass. To get an idea about how much this energy is, they have collected that huge list of energies associated with everyday objects on the left scale.

After referring to the scale, you’ll find that the amount of energy that is theoretically stored in the mass of a sand grain is almost equal to the energy that is needed to move a family car by 10 km. Even though you don’t really have an access to all that energy, Isn’t that huge, for a “very fine sand grain”! Check out the scale to see how huge things can get…

What I appreciate about it

Firstly, I appreciate the amount of effort it would have taken to collect that sort of data. I know that because I’ve tried doing something similar once. Trust me, It is a pain!

Secondly, I appreciate the fact (and again the effort) that their media is made using the latest web technologies. This makes their media so accessible to people.  Today, all you need for learning science, is an internet connection and a nice browser, like Chrome or Safari.

Besides this particular media (Mass-Energy scale) they have created, there are a couple of others that have already been up and running since the start of this year. I’m sure, like me, you’ll have a couple of hours of fun, learning and playing around with them. Cheers to simplified science and MinuteLabs for doing this project.

A Request

Build an Autonomous Toothbrush Robot in Minutes

By Anupum Pant

Background

If you are looking for a cool little science project, I think your search should end right here because today I’m sharing with you an awesome way to transform your toothbrush into an autonomous toothbrush robot. This one is just autonomous enough to move around on its own, hit obstacles, turn around and continue. But remember, since it is a fun project that can be completed within minutes (in under $5), you can’t expect a lot out of this basic bot.

Also, I did not invent this thing. I happened to stumble upon a video by Evil Mad Scientist on YouTube that taught me the basic idea of how this thing works. So, cheers to him. However, since my supplies were constrained, I felt a need to find some alternative methods to construct a similar bot. I’ve shared the original video and my own alternatives (in text) under it… You can skip reading the next two sub-headings and watch the video below them.

Here is what you’ll need:

  • A toothbrush (preferably, one with angled bristles)
  • A cellphone vibrator motor
  • Some double side tape
  • and a Button cell

Here is what you do:

Firstly, do not worry if you don’t have the exact materials mentioned above, I’ve suggested some alternative ideas after the video.

Stick on motorCute but unstable

  1. Grab the toothbrush and carefully cut off the handle, we’ll just need the head. Now, this part can be the most difficult because the plastic at the neck can be pretty tough sometimes. If you are not confident, take help from an elder.
  2. Use the double side tape to stick the motor on top of the head in a way that the rotating shaft of the motor doesn’t touch the bush.
  3. Connect the button cell to the terminals of the motor. If the whole bot starts vibrating with the motor, It’s done. Place it on the floor and watch moving…

Alternatives

  • Suppose you don’t have a brush with angled bristles. You can just take any other toothbrush and keep it under your mattress for a day to get pressed. The straight bristles turn into angled bristles. I had to do this, so I know.
  • Now, if you don’t have a cellphone vibrator motor, you can use one of these common motors too. All you’ll have to do is stick a piece of clay or tape on the shaft to make a counter weight so the motor vibrates when it rotates. You don’t want it rotating smoothly here.
  • To make the bot turn away better from obstacles, I stuck 3 toothpicks on top of the brush in a way that one of them was sticking out in the front and the other two were pointing out from the sides to form wing like structures.

It hardly takes any effort to try it out and then you’ll have your own bot moving around on the floor of your house. It feels great to watch it move like that! If you can, try making a huge variant. Use a bigger brush, pencil batteries and a bigger motor.

The Science of Blogging Better – for Newbie Bloggers

By Anupum Pant

The following is not a cheat sheet to double visitors, conversions or rank better on search engines. Like AweSci’s tagline says, this article is meant for “being a better person through Science”.

Even though I’m doing good with Google search results, I’m not much of an SEO enthusiast. I blog because I love to do it. I don’t like to craft posts to trap clicks from a search engines. I write about things that really interest me, and not necessarily about the things that are most searched.

However, I don’t mind making a few logical alterations to my style, that would NOT change the kind of articles I really want to write, and at the same time would add better value to people reading it. My aim would be to write for that person, who would search for something on Google, would end up here, and thank me for giving him/her the answers he/she was searching for. That would make me a better person.

The science of it

Blogging gurus will tell you to “produce quality content”. To break down the meaning of “quality content” in a detailed way is impossible in a single article. However, here are some of the most important things that will turn your content into “quality content”. The two major studies I discuss here are no less than full-blown psychological studies (is the reason I put it in the Psychology section) – They don’t mention the hard science separately, but they essentially deal with the psychology of your readers.

While going through a blogging guru’s blog yesterday, I noted the following interesting things that can clearly help you newbie bloggers stand out and create real value on the internet. And I think it is worth knowing. For millions of people out there looking to start a blog, or the ones have just started blogging, a careful initial look at “Blogging” with the magnifying glass of science would definitely make them better people on the internet. That, I think, should be anyone’s aim with a blog. So, here is the basic science of blogging better – Continue reading The Science of Blogging Better – for Newbie Bloggers
