Nanotechnology in the Military

Here we are, continuing with the topic “Nanotechnology”, and today’s theme is going to be “Nanotechnology in the Military”.

As I said in the second-to-previous blog post, scientists believe that Nanotechnology holds a very big potential and with this potential it can help the military. But how? Now let’s see how it can help in the military.

First, with Nanotechnology a much more effective armor can be built, much lighter as well, and it would be built with flexible fabric that would be like water, it would absorb the energy of the bullet. Also there would be invisibility suits. What about the weapons? There wouldn’t be ordinary guns. There would be nano bombs like “mini nukes” and the “Nanothermites”.

Overall, the whole military would be changed with the nanotechnology, and how the time goes there are much more effective “products” that are made.

On what topic should I write about next? Tell me in the comments!

Women in Science

Here we are, today continuing with something different, and as you can tell by the topic that is going to be “Women in Science”. So let’s begin!

You have probably heard of many, many men scientists, but do you know many women scientists? You probably do not. Are there just a few women scientists or there are many but we don’t know them? The actual answer is that there are many women scientists but we don’t know them. Why is it like that? The answer is simple! Many men take the credit for the work many women have done. As the time passes, this changes. Now people know a lot more women scientists then they did before. Also, as I said, there are many cases where men took women’s credit of finding something. That is the case of Rosalind Franklin where she took an X-ray photo of the DNA’s structure but it was shown to two male scientists who received recognition instead of her.

Here is a video about women in science:

There is still discrimination because the female scientists aren’t paid as much as male scientists are.

Basics of Nanotechnology

Here we are, continuing with the next topic, and that is going to be Nanotechnology. Yes, we’re getting into tiny things that can do wonders. But first, let’s get into its basics.

Nanotechnology is creating very small machines, using today made materials to make complex products. With nanotechnology we will be able to affect the matter, and with that we can help the military, the medicine and stuff like that.

Atoms are the building material of everything, and by using nanotechnology we can affect the atoms. This takes us to a conclusion that we can create a material from using totally another material; we can build something out of something else.

Everything has a future including the nanotechnology. But, what is the future of nanotechnology? Scientists say that nanotechnology has very big potential and with that in mind, by creating more complex machines in the future with nanotechnology we can get solutions for many problems like medicine problems, small production of energy, small nutritional value of the food and etc…

Quantum Entanglement

Here we are, continuing with the topic “Quantum Physics”, and today’s theme is going to be “Quantum Entanglement”.

To understand the Quantum Entanglement, several ideas and words must be explained. The photon is a key concept in physics, and so critical to entanglement that its behaviors must be fully understood.

What is a photon? – A photon is a force carrier particle. Elementary particles (electrons, protons, neutrons, and such) can only interact using force carriers. In the race analogy, photons are like fruit; they are responsible for electromagnetic interactions.

Polarization! – Polarization is the direction in which photons oscillate. In physics, to oscillate means to vary between alternate extremes, often within a set time limit. For a photon, its polarization is the orientation of its axis, which in turn is linked to its direction of motion.

When a photon (usually polarized laser light) passes through matter, it will be absorbed by an electron. Eventually, the electron will return to its ground state by emitting the photon. Certain crystal structures increase the likelihood that the photon will split into two photons, both of them with longer wavelengths than the original. Keep in mind that a longer wavelength means a lower frequency, and thus less energy. The total energy of the two photons must equal the energy of the photon originally fired from the laser (conservation of energy).

When the original photon splits into two photons, the resulting photon pair is considered entangled.

The process of using certain crystals to split incoming photons into pairs of photons is called parametric down-conversion. Normally the photons exit the crystal such that one is aligned in a horizontally polarized light cone, the other aligned vertically. By adjusting the experiment, the horizontal and vertical light cones can be made to overlap. Even though the polarization of the individual photons is unknown, the nature of quantum mechanics predicts they differ. If an entangled photon meets a vertical polarizing filter, the photon may or may not pass through. If it does, then its entangled partner will not because the instant that the first photon’s polarization is known, the second photon’s polarization will be the exact opposite.

It is this instant communication between the entangled photons to indicate each other’s polarization that lies at the heart of quantum entanglement. This is the “spooky action at a distance” that Einstein believed was theoretically implausible.

Quantum Physics and The Double Slit Experiment

Hey guys, I’m back and with me I’m bringing you the first topic and that’s going to be Quantum Physics and The Double Slit Experiment. Noo… don’t go away, I’m going to be showing you just the interesting part of it!

But first, what’s Quantum Physics? Quantum Physics, simply, is a type of Physics that studies the behavior of particles on atomic and subatomic level. Well, what the heck is now The Double Slit Experiment? Did you know that understanding this experiment can truly change your views on life?

To understand this experiment first we need to make difference between particles and waves. Particles are what we know as matter, something with mass. And waves are like disturbed substances. If we shoot a stream of electrons through one slit we get one band on the back wall. That’s normal, right? Now, if we shoot a stream through two slits we should get two bands. But no, instead of getting two bands we get an interference pattern and many bands on the back wall. That’s crazy, right? Physicists thought that maybe electrons are hitting each other and making that pattern. So, they decided to shoot one electron at a time. Can you guess what happened? After an hour of shooting they got the same pattern!!! They supposed that the electron becomes a wave, goes through a slit, and interferes with itself. So physicists put a measuring device by one slit to see what’s going on there. When they put a measuring device ( that is a camera) to observe which slit the electron actually went through. At this point the electron decided to act like a particle, not like a wave. It produced a pattern of two bands. The electron decided to act differently as it knew it was observed.

Here is a video explanation of this experiment

So what does it mean? Does the observer create particles simply by observing? Are we creators of the reality we call material? If electrons can appear in superposition as waves, can people appear in two places at the same time as well? There are so many mysteries surrounding this experiment!

I’m so glad if you understood this experiment and this explanation of this. There is a “tiny” conclusion and if you know it, be sure to tell it in the comment section!

Stay tuned, and ..er what do you want to be the next topic?

Introduction!

 Hey guys my name is Martin Ristoski, a student from Tetovo, Macedonia. I’m 13 years old and I love Science, so I made this blog about Science.

In my mind I have so many things to write about Science, but I think that the most interesting part is write about the CUTTING EDGE Science and the MOST INTERESTING FACTS ABOUT it. I will show you some pictures and videos of new wicked inventions that can change the world including new theories about the universe. There will be many branches of Science like: Physics, Biology, Nanotechnology, Astronomy etc.

That’s just the beginning of my blog, but if you have some new ideas that you want me to write about, don’t be shy and please comment about it in the comment section!

Stay tuned for some cool stuff coming up soon…
