Upside-down Shadows: An Interesting Phenomenon

You viewers are no stranger to the pin hole camera you might have studied in your 6th or 7th grade, where it inverts the upright image. The concept of convex and concave lens is also familiar to you. The image formed by convex lens is inverted and that formed by concave lens is upright. Inverted images are usually formed on the screen…(Ok, I’m going to far). Coming back to the topic, you’ve heard of and seen inverted images, but I bet you must have not seen your own shadow being inverted.

Nanotechnology: The Anticipated future

”Why can’t we right all the 24 volumes of the Encyclopedia Britannica on the head of a pin?”, asked Richard Feynman.

Science has developed since the birth of the universe, but we slowly knew them after the birth of humans, birth of famous scientists, thinkers, and many more. But, there is a difference. Science of today has more difference than science of yesterday, and science of yesterday has more difference  than science of day before yesterday. Like that, science has changed so much in the past that we are able to enjoy the technology that we have today. Science has produced so many thinkers that they are able to anticipate the future which awaits for the human beings and of course, our planet Earth. Albert Einstein and Stephen Hawking were two great examples of thinkers, who were able to ‘simulate’ the future in their minds themselves. What technology awaits for us, then, in the future, you might ask? Yes, the future technology: Nano technology.

Are there really 3 states of matter?

You are all no stranger to the concept of matter and states of matter. We generally use water as the main tool to explain this states of matter concept in a simple way. We also know there are 3 states of matter, namely, solid, liquid and gas. Water exists in those three states of matter, as ice, as itself and water vapor, respectively. But, a geek tells you that there are MORE than 3 states of matter, and you confidently tell that there are only 3. But, me being that geek I told you in my example, argues. Are there really 3 states of matter?!? It’s crazy, right? What can those other states of matter be? So, let’s discover those stuff on this confounding topic on the other states of matter!

Biological Immortality

I’m pretty sure you viewers must have gotten happy on seeing the word ‘immortality’. All of us don’t want to die, right? Sadly, we have to, also, the topic on which I’m talking about, ‘Biological immortality’, only applies for other special animals, not us humans. Why not us? Is there a way we can ‘revive’ after death? All the questions will be answered on this amazing article on this amaaaazing topic!

Vocal anatomy is not the cause for monkeys not to speak

A group of international researches found out that they have contradicted the fact that monkeys cannot speak because of its limitation of its voice box, and that it’s not as developed as humans. But, it’s not.

Monkeys and apes are believed to be Man’s closest ancestors. They lived like us in associations. But, there was a difference. Man could speak well, and apes could not communicate in the ‘desired’ language. And, this was believed to be because of its voice box and vocal cords. It was said that its vocal anatomy, which is comprised of the voice box, the vocal cords, the tongue and the lips, had limitations.  But, it was later discovered that it was not because of their problem in their vocal anatomy, but of their brains.

A brief study on atoms

I asked myself one day: If we are made of cells, then what are the tables, chairs, your pencil box, the pencil, the lead of the pencil made up of? Of course, I had the first thought in mind that obviously, the tables and chairs are made up of wood or plastics, the pencil box made up of either a plastic or metal and the lead of the pencil is of graphite. But, there’s a catch:  What are the  plastics, or the metals made up of?

So, this question is better answered with…lego bricks. Ok, here’s a pic of the famous lego bricks.

Lego blocks

Now, take the example that you are making a car with these bricks. Each brick constitutes to the making of the car. So, in Science, atoms are the building blocks of a substance. Here, the lego brick is one atom, which are joined to other bricks to make another new substance called molecules. So, molecules are just two or more atoms joined together.And, these molecules are called elements when they cannot be furthur broken down, or should I say, in the context of maths, reduced? When elements are chemically processed and are joint, it forms a compound. If they do not react, they are called mixtures. So, that’s all about the external parts or things about atoms. Now, the internal part. Brace yourselves.

Mummified remains identified as Egyptian Queen Nefertari

161202094342_1_540x360

A team of international archaeologists believe a pair of mummified legs on display in an Italian museum may belong to Egyptian Queen Nefertari — the favourite wife of the pharaoh Ramses II.

The team, which included Dr Stephen Buckley and Professor Joann Fletcher from the University of York’s Department of Archaeology, used radiocarbon dating, anthropology, palaeopathology, genetics and chemical analysis to identify the remains.

They conclude that “the most likely scenario is that the mummified knees truly belong to Queen Nefertari.”

As the favourite wife of the pharaoh Ramses II, Nefertari was provided with a beautifully decorated tomb in the Valley of the Queens to which Professor Fletcher was recently given access.

Although plundered in ancient times, the tomb, first excavated by Italian archaeologists in 1904, still contained objects which were sent to the Egyptian Museum in Turin.

This included a pair of mummified legs which could have been part of a later interment as was often the case in other tombs in the region. But as the legs had never been scientifically investigated, it was decided to undertake the recent study to find out if the legs could actually represent all that remained of one of Egypt’s most legendary queens.

The study, published in the journal Plos One, revealed that the legs are those of an adult woman of about 40 years of age.

Dr Buckley’s chemical analysis also established that the materials used to embalm the legs are consistent with 13th Century BC mummification traditions, which when taken in conjunction with the findings of the other specialists involved, led to the identification.

Professor Fletcher said: “This has been the most exciting project to be part of, and a great privilege to be working alongside with some of the world’s leading experts in this area.

“Both Stephen and myself have a long history studying Egypt’s royal mummies, and the evidence we’ve been able to gather about Nefertari’s remains not only complements the research we’ve been doing on the queen and her tomb but really does allow us to add another piece to the jigsaw of what is actually known about Egyptian mummification.”

Research is being continued and mummies are discovered and identified, and slowly,the past is also being reformed. We are slowly getting to know the truth, and the lie.
