Cutting a Round Cake on Scientific Principles

By Anupum Pant

Background

For years the phrase “cake cutting” has conjured up just one image in my brain – A triangular section of the cake. This way of cutting a cake is so normal that even the tools (especially the spatula) that are made for cake cutting are made in a way that’d work with best when you are making that traditional triangular cut. Turns out, this method of cutting a cake which we’ve all know for years is totally wrong.

Why is it wrong?

It’s wrong mostly for mathematical loners. People who, on their birthday, have no one around to share the cake with, and cannot finish off the whole cake. For them and the ones who have to store the cake after cutting it, are extremely careful about how moist the edges remain when they next eat it, this right way to cut a cake might be of great importance.

The way we’ve always know is “wrong” because when you cut off, say a single section of the cake and decide to store the larger piece in the fridge, some internal part of the cake remains exposed and it dries off. So, the next time you cut off a piece near the area where you started, you’d get a freshly cut moist wall of cake on one side, and a repulsively hard dried up wall on the other. That, some think, is extremely unpleasant.

What’s the Right way?

About 100 years back, a brilliant Polymmath (and a mathematician), Sir Francis Galton, faced a similar annoyance. So, instead of cursing others for having invented an absurdly inefficient way to cut a cake, he decided to develop his own. He ended up developing a very simple and efficient cut which helped him keep the cake wall relatively moist. Here’s how the cut works. (Cut along the dotted line)

the right way to cut a cake

Describing his new way of cutting cakes, he got an article published in the Nature magazine (dated December 20th, 1906). “Cutting a Round Cake on Scientific Principles”

Revolutionary – A Simple Yet Much Stronger Artificial Muscle

By Anupum Pant

Background

Some things are just too simple to be noticed by most adults, rather a child would notice it better. Scientists are the ones who manage to hone their ability to  look at things like a child would see it – Children of course are the best scientists. That is what makes scientists different from most other people. And that is what helps them make elegant discoveries, like the one we are seeing here today.

Now, this may seem like a useless thing to some, but in reality the simple fishing line muscle is a huge step towards creating affordable personal robots, exoskeletons and a host of other earth changing devices. I can’t stop thinking how massive this simple thing could end up being.

The Discovery

A team of researchers at the University of Texas at Dallas, did exactly that. In a simple nylon fishing line, these researchers saw something that everyone till date has failed to notice. They noticed that, by twisting a nylon line into a coil (and heat treating), they could turn it into an artificial muscle. Later it was learnt that a simple artificial muscle made in this manner is about 100 times stronger than a human muscle and can go through millions of cycles without failing.

It’s actually so simple to do that you could make an artificial muscle in your own home. In fact, it works with a variety of other kinds of materials too, but better stick to the tested fishing line for now.

All you need to do is to hold one end of a long fishing line and start twisting the other end (a hand mixer could come in handy here). At some point the line reaches a point where it can’t twist any more, and then it starts getting coiled into a telephone wire kind of a spring. Now it can be heated in an oven (carefully, without melting) and cooled to lock it in this coil shape. There, you’ve got your own artificial muscle.

Working

Unlike what you think it would do when heated, the coil actually contracts and can lift a good amount of weight. An array of such artificial muscle fibres could lift a much heavier weight. as shown in the video below.

At first I found it confusing. It was hard for me to understand, what physics goes inside that makes the coil contract as a whole when it is heated. From the words of a wise scienitist, I found that it works like a chinese finger trap (and then I had to look what this piece of origami was). Whatever the coil does is absolutely elegant. It’s almost impossible for me to explain in words how it works. You might have to watch the video below…

The catch is that the nylon muscles made in this manner are very inefficient, but that can be worked upon.

Killer Lakes – A Very Weird Natural Disaster

By Anupum Pant

In the Northwest Cameroon (Africa) there’s a lake which is commonly  known among the locals as “The Bad Lake”. The official name of this lake however is, lake Nyos. This is one of those three or four special lakes in the world which are mostly know for their mass killings. The locals living near the lake Nyos in particular have a very grim story to tell from the past.

The Story

A seemingly innocuous landslide occurred on August 21st, 1986. This created a mini tsunami and sent red water (due to iron) flying 300 feet in the air. There was nothing really dangerous about the flying water. But, as a result if this landslide, it is believed that about 1.2 cubic kilometres of carbon dioxide from the lake Nyos got released. The trigger could have been something else, but the gas that got released was carbon dioxide for sure.

This rare kind of a natural disaster is known as a Limnic Eruption or Lake overturn. There are just 2 other lakes known where scientists think this can happen – Lake Monoun, Cameroon, and Lake Kivu of Congo

The huge amount of CO2, being heavier than air, spread into the nearby low-lying villages in a range of 25 km. People had nowhere to escape and nearly everyone died. Only a few hundreds who acted quick, and escaped to higher ground on vehicles could save themselves. That day, 1,700 people and 3,600 livestock got suffocated to death.

Why it Happened

volcanoLake Nyos like only a few other lakes in the world was formed about 400 years ago on a huge crater. Far below the lake there’s magma and it spews CO2 continuously into the lake, forming huge amounts of carbonated water (a good thing for Coke lovers). The CO2 doesn’t usually release in a single go all the time. It happens gradually, and the pipes now installed to fix this keep releasing CO2 all the time (The pressure of gas also carries water along to form a beautiful fountain).

Sometimes however, due to some triggers, the CO2 can get released in a single go and cause the absurd natural disaster which ends up killing thousands.

The Lake Kivu which is in Congo probably holds a much worse headline for the future. This one is about a 1000 times larger than lake Nyos and is surrounded by heavily populated towns. There’s magma below it too and any sort of disruption could cause massive amounts of carbon dioxide to release into the nearby towns. To add to the fears, researchers have found that the massive lake Kivu’s life goes extinct every 1000 years. We can only wait and watch what happens…

An Incredibly Simple Way to Kill A Tree

By Anupum Pant

Background

Of course, killing a tree is something I’d never want to do. I see them as old and wise people who have grown and matured for years. Plus they give us so much in return. And yet sometimes, they say, there are good reasons to kill a tree. I’ll probably never understand.

Anyway, I thought it’s good to know, just for the sake of knowing that there is an incredibly simple technique that is often used to kill trees (for legit reasons) and is widely known among horticulturists. I learnt about it just today, and I felt it was worth sharing.

It’s called Girdling (also known as  ring barking or ring-barking). Or, a technique which involves removal / peeling of a ring of bark from a tree, and the phloem layer (Like shown in the picture above). Yes, that’s it, this kills a tree. And it’s slow death. A tree which gets girdled dies gradually in about a year or more.

This is why it works…

The central part of the tree trunk (wooden part) is involved in taking the nutrients and water up to the leaves. The leaves then get exposed in the sun and mix in carbon dioxide to make sugar and other reduced carbon compounds. Most of us know that. But this is what not many know…

The outer part of the trunk – the bark and the phloem layer – also has a solid function that sustains growth and function. It’s responsible to carry the sugar (and other stuff) made by the leaves, back to the root. That is basically food to sustain growth and function of the roots. If that doesn’t reach the roots, the roots don’t receive what is required for their growth and function. Girdling does exactly that – cuts off the down-flow of food. As a result, the root dies and with it dies the whole tree. All of this happens very slowly.

To be noted

Jumping the Girdle: Some times, trees are able to repair this damage. It’s called a jumped girdle. To prevent that from happening, often smear herbicide over the girdled area.

Better Fruits: This technique is also used by some farmers to force the tree to bear better fruits – as no sugar goes down into the roots – the fruits are usually bigger and better if they come from a girdled tree. Of course these better fruits come with a price.

Girdling is particularly a good way to end trees like Aspens because as we know from Pando, many other Aspens can sprout up from the roots and cause a bigger mess if just the top part of this tree is cut off.

Girdling is a better way to kill a tree because it gives the environment time to adjust, also it is cheaper and prevents damage to the other delicate plants around the tree.

The Leaping Shampoo Trick – Kaye Effect

By Anupum Pant

This is really interesting and I can’t explain why. You’ll have to see it for yourself.

Long time back, researchers at the University of Twente in The Netherlands thought of something very weird. They decided to drop a thin stream of shampoo from a height of about 20 cm, ended up discovering an absurd physical effect and winning great accolades for it – The Kaye effect.

The seemingly weird effect can fairly easily be achieved at home by dropping a thin stream of shampoo on a relatively hard surface. In individual steps, this is what happens when you do it:

  • As the stream gets collected, it forms a little shampoo heap.
  • Amazingly, and counter-intuitively, a secondary stream ejects off the heap.
  • The mythical secondary stream becomes bigger, shoots further.
  • And finally hits the incoming stream – this collapses the Kaye effect.

Of course, everything happens really fast. But, if you look at it on extremely slowed down film, you’d see the individual steps happening one after the other.

True, the secondary stream collapses too quickly, scientists weren’t happy about that either. So, they tried tilting the hard surface slightly to achieve a stabler version. Lo! And they had a stable Kaye effect.

This happens because due to certain physical forces the viscous liquid becomes slightly less viscous temporarily – they call it shear thinning. As a result, it causes a new stream to emerge. May be the same effect could be achieved with other thicker liquids like lava, ketchup, whipped cream, blood, paint, and nail polish. But, then lava is too dangerous, and others (barring blood and paint) seem to be too thick. I’m guessing, dropping thicker ones from a higher place could make this happen.

If you find this interesting,you’d definitely love the egg and milk effect, also the chain of beads defying gravity.

Eye of the Sahara – A Geological Mystery

By Anupum Pant

Unlike the great wall of China, this huge eye-like geological formation in the Sahara desert is actually visible from the space. In fact, it wasn’t even discovered before the space age.

The Richat Structure, or as some say, eye of the Sahara, is a deeply eroded and a slightly elliptical formation in the Sahara desert near Ouadane, west–central Mauritania. The whole structure is approximately 50 km wide and has several concentric formations. Since it is so large, it wasn’t identified till the astronauts saw it from the space. Here’s a google satellite image of the structure.

Some other times, people have also called it the Blue eye of Africa. That is because in some images taken by the NASA, the geological formation looks blue in colour.

Although the formation itself is an incredible thing to watch, there’s something more astounding about it. No one till date has been able to explain the reason behind the formation of this huge blue eye in the centre of the desert.

Since the formation is very circular (not too elliptical), some say that it was formed due to a asteroid strike. That theory however has been debunked and  it was said that it was probably formed due to a volcanic eruption. And as there is no evidence of any igneous or volcanic rock in that place, the volcanic eruption theory doesn’t work too.

Other interesting point of view is that the almost equidistant concentric rings from the centre might be so symmetrical because they were probably man-made. Also, the whole formation seems to fit the description of Atlantis given by Plato. Although it seems highly improbable that this was the city of Atlantis, it is still a very interesting way to look at it.

Anyway, there’s a lot to be studied about it, but the inaccessibility of the place makes it harder. Maybe in the near future, scientists might be able to find what actually caused this geological formation.

Australian Bird Makes Camera Shutter Sounds

By Anupum Pant

Until now I hadn’t even heard about, probably the most well-known bird of Australia, the Lyrebird. These birds are there on the 10 cents coins in Australia. Their feathers are beautiful, but what these birds can do is truly astonishing – The R2D2s of the real world.

The Lyrebird has been seen mimicking the sounds of at least twenty other birds. That’s not all. Some of these captive Lyrebirds have been seen mimicking sounds of human technology like a camera shutter, car alarm and a chainsaw too – as seen in the video below.

In 1969, as observed by an ornithologist in New England National Park, these birds were able to reproduce sounds of a flute, singing two famous songs of the 30s “The Keel Row” and “Mosquito’s Dance.”  They had learnt it from a farmer who used to play these tunes on a flute.

A word of caution

Although the video would lead you to believe that wild birds have started mimicking sounds of human technology, it isn’t totally true. The birds that has been shown in the video, in reality, are captive birds from Healesville Wildlife Sanctuary and from the Adelaide Zoo. While Attenborough makes it seem like the bird is mimicking “sounds of the forest”. these clips are not typically what these wild birds do in the wild.

Maybe it happens in the wild too, but it’s highly unlikely because the human technology sounds are usually lost amidst the forest sounds. Moreover, never in the past has there been a recording of this bird mimicking human technology sounds in the wild. Maybe they do, but science requires evidence.

Brass Doorknobs of Public Restrooms

By Anupum Pant

I remember my grandma telling me to keep some water overnight in a copper pot, and in the morning, she used to drink it. I never understood why she did that. Backed by solid science, today I’m able to appreciate her age-old wisdom.

Today, to get rid of the problem causing bacteria, trusting brass doorknobs is better than trusting those triclosan lad anti-bacterial soaps. Yes, brass can kill bacteria very effectively.

Doorknobs are probably the most touched objects, especially the ones that are on the doors of a toilet at the mall. A doorknob probably even beats smartphones because a doorknob is accessible to anyone and everyone, whereas a smartphone is usually touched by a single individual.

Although, I’m not totally sure that a doorknob is really one of the most touched objects, one thing is for sure – Door knobs are the places where an incredible amount of sickness causing germs get collected. Thanks to the thousands of unclean hands coming straight from the toilet and touching the knob for the day.

And yet, you don’t often get sick after touching public restroom knobs. That is because doorknobs are normally made of brass. Brass and a couple of other metals have an ability to clean themselves – in a given amount of time these metals are able to sterilize themselves! This is called the Oligodynamic effect. Sounds like a cool name to remember because it’s easy to remember and nothing else would annoy your friends more than you bringing it up amidst conversations…

It has been tested and found that brass is able to sterilize itself in the span of eight hours. While some have tried to explain how it works, no one has been able to explain the effect in a satisfactory manner.

Other metals like silver, copper and copper alloys are able to kill bacteria better. Silver, purportedly is a very robust disinfectant. But, not many would be able to afford doorknobs made out of silver or pure copper. Instead, a far cheaper alloy consisting of copper and zinc (brass) is used to make bacteria zapping doorknobs.

Stainless steel and aluminium metals aren’t able to do this. Be careful when you have to twist doorknobs made of Steel or Aluminium. These are metals that could get you sick.

2000 Year Old Extinct Tree is No Longer Extinct

By Anupum Pant

At Herod the Great’s palace in Masada, Israel, from the year 1963 to 1965 an excavation was carried out. It was an excavation which blew everyone’s mind. As a result of this archaeological endeavour, an ancient jar containing date palm (Judean Palm) seeds was unearthed. The radio dating of these seeds confirmed that they were about 2000 years old. Like all other excavated material, the seeds too were sent into a safe storage at the  Bar-Ilan University. For the next 40 years, these seeds remained in the storage.

The seeds which were unearthed belonged to a plant which in its time had flourished for thousands of years. Around 150 AD the tree went extinct. None of them remained. However, the seeds did…

In the year 2005, a researcher, Elaine Solowey, decided to plant the seed. Elaine was pretty sure that a 2000 year old seed would be totally dead by now, and there’s a little chance it would even sprout. She went ahead anyway.

Elaine did a deep research on how to revive old seeds. Then, she first soaked them in hot water. And then in a nutrient rich solution. Finally they were put in contact with an enzymatic fertilizer.

To her surprise the seed did germinate. But when it did come out, Elaine was pretty sure that the sapling would die out. It didn’t. Although there were claims of a 32,000 year old germinated seed later in the year 2012, in its time, the Judean palm’s name had gone into the record books as the oldest seed to have ever sprouted…

The tree has been named Methuselah after the oldest person named in the Old Testament of the Bible. Today the plant still continues to grow and has even made its first flowers.

Six Weeks and Ten Factorial – Bizarre Math Coincidence

By Anupum Pant

The number of seconds in 6 weeks might be of little importance to anyone. However there is an interesting bit of trivia related to it, or call it a bizarre mathematical coincidence. Here it is…

The number of seconds in 6 weeks, or 42 days (The answer to life universe and everything) equates to:
6 X 7 (days) X 24 (hours) X 60 (minutes) X 60 (seconds) = 3,628,800 sec
The number 362,880, on the first glance, looks like very random number. Now here is what this number is equal to…

10 factorial (denoted by 10!).
Or simply, 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1 = 3,628,800

Down to a single second, the number of seconds in 6 weeks is exactly equal to the numerical 10! Very strange!

One thing you could do is split the 6 weeks calculation into factors, and see it for yourself. The result is all numbers from 1 – 10. The most amazing factoring I’ve ever seen.

If you are too lazy to calculate it yourself, go to this WolframAlpha calculation and see it for yourself. It subtracts 10! seconds from 6 weeks (the result is exactly 0). Apples and Oranges, I know, but the 6 weeks refers to seconds in 6 weeks, here.

Stop Trusting Everything You See

By Anupum Pant

Background

Everyone who comes on this blog often knows that I’m a huge fan of Prof. Rischard Wiseman. If you don’t know that, well, I urge you to check out every other post where I’ve mentioned him (Yes, he’s the same man who makes videos for the YouTube channel 59 seconds). The man certainly knows how to play with your brain. And once again he has blown my mind with this amazing optical illusion that he shared on his blog.

This is probably the best optical illusion I have ever seen. That is because, it’s somewhat like the Mc Gurk effect (do check it out too) – in a way that, it is one of those illusion where even after you learn about it, you still can’t see through it. I mean, it will continue to fool your brains, even when you know the trick. It’s an eternal magic trick. Enough of the build up. Now, let’s see what this illusion really is…

Wash your eyes if you have to

In the image below, you’ll see a pinkish swirling image and inside it you’ll see that there are green swirls and blue swirls embedded. What if I tell you the green and the blue you see are the same colors? Just because I’ve written something that’s completely opposite to what you see with your own eyes, you’ll probably laugh on my face and call me mad. I did that. I trusted my eyes more than any one else’s word. So I had to verify it…

most amazing optical illusion

The Proof


greenblue2Ok, if you take my word for it, fine. If you don’t believe me, you could use a simple image editor, pick colours and check. Both the colours you see here, green and blue, have the same hexadecimal value: #00ff96.

Another thing you could do is, download the image, zoom it to a great extent, such that both the colours that you see are in the same frame and you’ll see that the colours are actually same. Here’s a picture of that zoomed part…
 bluegreenzoom

optical illusion proofHere’s an image I created where we have the #00ff96 coloured square overlapping the seemingly blue and green parts. If you, cover everything except the topmost corner first, look at it carefully, and compare it with the bottom-most corner, you’ll see that the colour of the square block perfectly matches that of both the “blue” colour and the “green” colour in both areas. And it is the same block.

The several other blocks in the middle are for you to remain sure that the colour of the block doesn’t change in between.

There’s another image in which it works…
Even here the blue and green colours are actually the same colours…

A Disease That Doesn’t Let You Sleep And Kills

By Anupum Pant

Background

In my very first article on this website, I talked about a 17-year-old boy, Randy Gardner who remained awake for an incredible 11 days and set a world record which no one had beat for a very long time. And then, in the 90s, Toimi Soini, of Hamina, Finland, set a new record of 276 hours of sleeplessness.

Well, no one should even try to beat it because depriving yourself of sleep can have some serious health issues and can even kill you. The seriousness of health consequences associated with such attempts is the reason that these records are no longer recorded in the Guinness books.

The disease

Not always do people decide to voluntarily break sleeplessness records. Some times, they can be the victims of a horrific and an extremely rare disease called fatal familial insomnia (FFI) – A progressively worsening form of insomnia discovered only 10-15 years ago. When it affects someone, the person starts having bouts of insomnia at first and then they aren’t able to sleep at all. Hallucinations, delirium, and confusional states occur and a person usually dies within 18 months from the first insomnia. 

The disease is caused due to a defective gene and the people having it start seeing symptoms from the age of 30 (never at an early age). It has been believed to have originated from an Italian man in the year 1765 (not necessarily).

Symptoms in detail

  • For the first four months there is an onset of insomnia and the person starts getting panic attacks and unfounded phobias.
  • For the the next 5 months the hallucinations become severe.
  • In the next 3 months, rapid weight loss and serious deterioration of mental ability happens,
  • Next comes dementia, unresponsiveness, and may be death.

[A list of couple of people who never slept]

Here’s a 10 minute documentary which discusses FFI in detail.

The Supercow of Belgium

By Anupum Pant

It’s hard to believe that naturally bred cows can grow enormous muscles. And yet, Dr. Patrice claims that by picking the cows with the best muscles over and over for generations, using selective breeding, they’ve been able to breed cows which don’t look like anything from the planet earth.

This gigantic breed of supercow they’ve been able to create has heavily developed muscles (not double muscles) and looks like a normal cow on steroids – with a sculpted and heavily muscled appearance (like in the picture). This breed of cows is called the Belgian blue.

To enhance the desirable characteristic of muscle mass in their beef cattle, the cattle farmers, for about a century, have picked only the cows with the most muscle mass, and have allowed them to mate, over and over. As a result, they now have the Belgian blue – a cow / bull that weighs a ton each!

First Man-made Object in Space – A Manhole Cover?

By Anupum Pant

Edit: The first man-made object to cross the boundary of space (100 km above the sea level, or the karman line) a Nazi German V2 rocket on October 3, 1942. – As mentioned by Scott and Adolf in the comments.

Background

Odd, I know. Teachers would say Sputnik was the first ever man-made object to orbit earth, but there is a slight possibility that Sputnik might not have been it – it could have been a humble manhole cover (not so humble, read on).

Back in the year 1956 (or summer of 1957, but definitely before the launch of Sputnik which happened on 4th October 1957), scientists at Los Alamos were learning to contain a nuclear explosion. To find out, they decided to do a much much larger version of the fire-cracker-in-a-can trick…
I’m not sure if they were doing it out of a desire to loft objects in space using a novel nuclear bomb propulsion, or it was something else, it sure was madness.

The mad experiment

In a 500 feet long and 4 feet wide vertical cylindrical tunnel, they put a nuclear bomb. The top of this tunnel was sealed using a 4 inch thick man hole cover (on steroids). The lid weighed about 2 tons! They were sure that even the 2 ton lid would blow off like feather due to the nuclear explosion. However, they weren’t sure on exactly how fast it’d travel up. To measure the speed, high-speed cameras were placed near the opening.

The bomb was detonated. Some say that the high speed cameras were only able to capture the image of the lid in a single frame. Which by the way could also contribute to an enormous error margin in the speed calculation. Nevertheless, the speed was of the lid at which it flew up in the air was calculated to be 41 miles per second – approximately 6 times the escape velocity! Never before had any man made objects moved at that speed inside the earth’s atmosphere. The lid went. It was never seen again. No one knows where it is now.

It’s highly likely that the lid was burned up and never reached Space. Or, may be it did reach some place and then dropped back. Again, must have got burnt during re-entry. Nothing can be said for sure.

Another thing that could have happened is that the lid went on and started orbiting the earth – highly unlikely, still. It’s probably still floating up there. And if things weren’t worse already, think of this – the first man-made object ever to orbit the earth was a manhole cover? Or, the fastest man-made object ever to travel inside the earth’s atmosphere was a manhole lid? Damn!

Outperforming Humans – Speed

By Anupum Pant

Humans can use tools, communicate, count, make others laugh, socialize and are self aware too. We also have emotions and a pretty good memory. All of the things put into a single creature sure makes the “most advanced” creature we’ve ever known. But if these traits are considered individually, you’ll easily find an animal who beats us at one trait at a time. Today, I wanted to read and write about where humans stand when it comes to speed.

Talk about running speeds and the fastest person ever, Usain Bolt comes to my mind. A bolt indeed. As on date, if I’m not wrong, the world record set by him in the 100m race is 9.58 seconds. To put this human freak show into perspective, the average speed of the Jamaican sprinter in this race comes to about 37 km per hour (23 miles per hour).  And he’s clocked 28 mph somewhere in the race, they say.

In a world full of cars and planes, where distances travelled have become really huge, 28 mph sounds like a speed which does no good in our practical lives. And yet, it takes an Olympic runner to clock that speed. Normally, people run at about, say 10 mph. Damn!
The biological human limit to running speeds is estimated to be about 40 mph.

Quick fact: The fastest human objects ever are Helios 2 (a German probe) clocks about 150,000 mph. Another spacecraft, Juno does about 25 miles in a single second!

Now compare that with a Peregrine Falcon which can make use of the gravity and its perfectly aerodynamic body to travel at a speed of 216 mph (360 kph). But, that’s hardly any work for the animal. It’d the gravity making it fall.

In level flight, the white throated needletail (swift) can fly at speeds more than 100 miles per hour (up to 106). That’s the fastest bird if you do not count gravity assist.

An on land, of course the Cheetah takes the prize with about 70 mph of running speed. But, there’s a catch. If you measure speeds of animals relative to their body sizes, there’s a little blood sucking mite that beats cheetah by a huge margin.

The fastest swimming fish is the sailfish, which can swim and jump for small distances at about 70 mph.

Humans can swim at about 5 miles per hour.

Moving at 35 miles per hour a jack rabbit can travel faster than a human. The patas monkey, the fastest primate, runs at about 35 miles per hour too!

Now these are some animals you probably already know. Soon there’s more to come. In the coming days I wish to do a series on outperforming humans…Maybe I’ll write about endurance next.

Keep reading for more.
