“WIND” Where it comes from?

Here I am after so long.. I have been busy with some really tight schedule.. Here comes the “reblogging my own age old” program again🙈🙈.. Rewind the article and stay connected until I start regular articles again …😄😄

We often enjoy the fast moving air so called “Wind”. But ever thought what makes air to blow? So, lets see what is happening… Wind is the air in motion. You can make your own wind by blowing air out of your mouth. When you blow air out of […]

Live forever “Frozen”(Cryonics)!

We have seen so many weird to the weirdest things in science, but I think nothing can be so weird than this. Basically cryogenics is the study of something in cold, but CRYONICS on the other hand is the study of some living thing kept in cold.

Cryonics is actually a process of preserving the human body in an extremely low temperatures, hoping that some day, science could be able to bring them back to life ( Technically called reanimation). “Hoping??” Yeah, this isn’t perfect yet, as of now scientists have only found the way to preserve the human body, but science has yet to improve further to bring the preserved human back to life!

You may ask, why on earth people want to live frozen forever? Well… The people with un-curable diseases hoping that science one day finds a cure or people just curious about future may end up preserving themselves through cryonics.

Now, let’s see what happens here rather how it happens. Once the person is dead, the cryonics team inject some antifreeze to protect the tissues from freezing because. The main problem here is our cells are full of water and when we freeze the body cells may freeze, when liquid freezes they expand so, there is a chance of breaking the cell membrane in this process. Then the body is cooled rapidly and finally kept in a liquid nitrogen container for too long.

It may take a few years or even decades to find a way to reanimate the human body (bringing the human back to life).

Science fiction is no more a fiction!!

 

 

Does cell phones cause tumour?

We’re swimming in a sea of electromagnetic radiation produced by electrical appliances and other technologies everyday, that are part of modern life.

Your phone sends radiofrequency, or RF, waves from its antenna to nearby cell towers, and receives RF waves to its antenna from cell towers when you make a call or text or use data. The frequency of a cell phone’s RF waves falls between those emitted by FM radios and those from microwave ovens, all of which are considered “non-ionizing” forms of radiation.

That means that unlike radiation from a nuclear explosion, the radiation from your phone does not carry enough energy to directly break or alter your DNA, which is one way that cancer can occur. FM radios and microwaves don’t harm us because they aren’t held close to your head when in use and because microwave ovens have shielding that offers protection.

Many studies were done and the results were not accurate. As of now there are more mobile phones than the total humans on our planet, which means the rate of tumour should increase as the cell phones are increasing, but it isn’t. 

In my view, cellphones are not that harmfull. Checkout my previous article on Radiation here (Most radioactive places on earth).

CES 2016!!

CES never disappoints us. In case you don’t know what CES is. Well… Every January we get to see future, literally the future of technology at CES (Consumer Electronics Show).

As usual, there are so many new gadgets and technologies around. In my view this CES was all about Internet of things( learn more about it here Internet of things ) , Drones, VR’s( a new htc vive, learn more about the previous vive here HTC VIVE ), Pixels(TV’s), a few cars, a special place for Benz concept self driving car( click here to learn more Benz) and a plenty of new technologies.

A real special place for EHANG 184, human sized drone. Check out the video below.

I didn’t actually experienced CES. So, here are a few trusted YouTubers showing a few technologies at CES 2016;)

“WIND” Where it comes from?

Here I am reblogging my own age old stuff to stay connected with you guys( my faithful readers), in my tough schedules likes this one… Hope you guys enjoy this new series of reblogging happening every week for four weeks. Until my EXAMS end…😵😵. Bare with me😜😜..

“LASER PRINTER” How it works?

We often use printers but, ever thought how it actually works? we select an image on PC and ask for a colour printer and boom you are done. You get an accurate copy of it in no time. Let’s see how..

Obviously first the printer transmits the data from the computer or data storage device as a digital file to the printer’s image processor.

Inside the printer, there is a drum that holds an electric charge. Next to the drum is a transfer corona roller, which can be negatively or positively charged as the drums requirement. In most laser printers, the drum starts out positively charged, although this process can also work in reverse. The controller throws out negative charge on the drum creating an “electrostatic image” of the digital file we chose to print.

laser-printer-laser

Then, the drum is rolled on a positively charged toner. Which when rolled it sticks to the negative charged part of the drum, which is the projection of the image drawn.

The electrostatic image on the drum will transfer to the paper with more negative charge, Then it is fed through a fuser, which heats the toner and causes it to bind with the fibers in the paper.

It sounds great right. Here comes the more interesting part..

How colour is printed?

Printers have blue, red, black, yellow etc.. which can be combined to form any color. Some printers progressively lay the ink onto the drum so that the image will print with one pass of the paper( same process as specified above), while others recirculate the paper multiple times to apply progressive layers of color. Large color printers sometimes have separate drum and toner assemblies for each colour, with the paper passing each drum separately.

Well… Today 15th September is ENGINEERS day. So, Happy Engineers day.. Today is celebrated as Engineers day in the remembrance of  Sir Mokshagundam Visvesvaraya in India…

Electricity by applying pressure (PEIZOELECTRICITY)

We extensively use electrical energy, probably we can’t live without it in this modern age. So, where do we get electrical energy from? Well, we got two ways Renewable energy sources( which are unlimited like solar energy), Non renewable energy sources( which are limited). Now the “Piezoelectricity” is something like Renewable energy.

What is Piezoelectricity?

There are certain materials called Piezoelectric material, which on applying mechanical stress produce electricity. Precisely apply pressure, boom you got electric energy.

How it manages to give Electric energy?

The animation down below explains everything.

Animation showing how piezoelectric charges appear when you press a crystal.

Animation source

Let us start analysing what our little animation is trying to explain. The Piezoelectric material is composed of equal number of electrons and protons so, the charges cancel out giving no net zero charge. As we apply pressure on this type of materials, the charges get out of balance and they end up giving some voltage at it ends.

This looks very simple yet very useful if used in a more specific and productive areas. And you can surely try this at home. Here’s the picture of piezo electric material (small one), go ahead connect it to an LED and start applying pressure on it and see what happens…

piezo2big

We can also make our own piezo electric material at home… Let me tell you how. Take Baking soda ( Sodium carbonate), Cream of tartar (Potassium Bitartrate). Mix 7:1 Cream of tartar to Water in a cup you should get a white solution, now put the cup in a pan with water and heat until it’s just simmering, now add half tea spoon of baking soda, it get bubbling keep stirring and adding baking soda until the solution becomes clear( transparent). Leave it overnight in a cool place. After an overnight stand you will get some crystals, something like this..

piezo-crystals

Try connecting these crystals ends to a multi meter, apply pressure to the crystal and test for some voltage…

so, let me know what do you think…

CRAZY EFFECT OF LIQUIDS…(Leidenfrost)

This is a crazy yet interesting effect of liquids.

Now, when a liquid droplet is dropped on a hot surface the water droplet evaporates instantly. We usually expect the same in case of a surface with more temperature than the boiling point of the liquid, but it isn’t happening. The liquid droplet hovers over the hot surface. This strange phenomenon is first discovered by a German physician, Johann Gottod Leidenfrost.

How this happens?

WaterDropOnHotPlate

Initially we see the droplets move around before they evaporate, after a while, we see the droplets skitter around the pan randomly. This happens when the temperature of the bottom surface exceeds LEIDENFROST point. When this point is reached the bottom surface of the water droplet evaporates very instantly that it creates a little insulating pocket under the drop through which the droplet hovers. As the droplet moves around on the hot surface molecules of the water start turning into vapour.

article-2442638-187FF8D900000578-395_306x281

Here’s still interesting thing, if a droplet is introduced on an incline of finely milled grooves live tiny stairs, the grooves will create just the right disruption in the vapour to move the droplet up the stairs (grooves).

This crazy effect of liquids have application in micro cooling electronics, ink jet etc..

Thanks to my friend Prathik for suggesting this topic..

6 DEGREES OF SEPARATION!! YOU ARE CONNECTED TO ANYONE ON THIS PLANET WITH JUST 6 LINKS…

Well… This is exciting, any two strangers on our planet are connected with just 6 links. It’s a small world. Yeah, we are all connected to each other. Even some great Scientists, Genius Entrepreneurs, Noble Laureates, Politicians, Celebrities etc… Are connected and can be reached within 6 links. This theory was first proposed in 1929 by the Hungarian writer Frigyes Karinthy in a short story called “Chains.”

six-degrees

In the 1950’s, Ithiel de Sola Pool (MIT) and Manfred Kochen (IBM) set out to prove the theory mathematically. Although they were able to phrase the question (given a set N of people, what is the probability that each member of N is connected to another member via k_1, k_2, k_3…k_n links?), after twenty years they were still unable to solve the problem to their own satisfaction. In 1967, American sociologist Stanley Milgram devised a new way to test the theory, which he called “the small-world problem.” He randomly selected people in the mid-West to send packages to a stranger located in Massachusetts. The senders knew the recipient’s name, occupation, and general location. They were instructed to send the package to a person they knew on a first-name basis who they thought was most likely, out of all their friends, to know the target personally. That person would do the same, and so on, until the package was personally delivered to its target recipient.

Although it was expected that, it would take at least hundred intermediaries but it only took between five and seven intermediaries to get each package delivered. Milgram’s findings were published in Psychology Today and inspired the phrase “six degrees of separation.”

In 2001, Duncan Watts, a professor at Columbia University, conducted an experiment on the internet through e-mail. Watts used an e-mail message as the “package” that needed to be delivered, and surprisingly, after reviewing the data collected by 48,000 senders and 19 targets (in 157 countries), Watts found that the average number of intermediaries was indeed, six.

We humans are kind of pebbles connected to each other randomly. Which means if we try to lift one pebble, all the pebble are moved. The fast growing technology made this even easier.

The first ever social networking site was “Six degrees of separation”. And now we have many social networking sites and we are connecting even faster. Some scientists predict that the 6 degree is reduced to 4 degree due to the fast building connections through plenty of social networking sites.
