Neutrinos travels faster than light, puzzling results from CERN

Today,in the morning, a ground breaking news has caught my attention- “Faster than light particle found ❗ , the scientists claim that ‘Neutrinos’ travels faster than light.” 😮

According to Einstein’s Theory of Relativity, nothing can go faster than the speed of light.
But the researchers on the Opera (CERN) claimed that- The pulse of hi-energy neutrinos sent through the ground from Cern toward the Gran Sasso laboratory (which is about 730km away), seemed to show up a tiny fraction of a second early.1 ReAd MoRe…

Double slit experiment – Journey to the Quantum universe

The double-slit experiment,  is a demonstration that matter and energy can display characteristics of both waves and particles. The basic concept of this experiment is very common to the scientist . If we send particles through one slit, we will get a line on the detector. If we use two slits and then fire the particles, we will get two lines on the detector. But what will happen if we send wave instead ? The answer is simple, we will find interference patterns on the detector.

Now lets jump to the quantum world, and fire electrons through the slit. You know electron is a small particle too.

Use a barometer to Measure the Height of a skyscraper !!

The following concerns a question in a physics degree exam at the University of Copenhagen:

Describe how to determine the height of a skyscraper with a barometer.

One student replied:

You tie a long piece of string to the neck of the barometer, then lower the barometer from the roof of the skyscraper to the ground. The length of the string plus the length of the barometer will equal the height of the building.

This highly original answer so incensed the examiner ReAd MoRe…

How to Annoy Your Physics Professor?

Well, today while surfing on the net, one page caught my attention. The heading was interesting- “Things to do to Annoy Your Physics Professor” 😛

I just share them in here. So enjoy the 25 things to do to annoy your physics professor :mrgreen:

1. At the same time during every lecture, slowly lift yourself up out of your chair and cry out, “Look! Anti-gravity!” As soon as the professor turns to look at you, let yourself fall back into your chair, shrug your shoulders and say, “Guess not.

2. Try to confuse him/her with sentences or questions containing a bunch of unrelated things, but sound like they could actually mean something. For example, “Why not just write the answer as ReAd MoRe…
