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…
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.
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…
Dr. Schambaugh, of the University of Oklahoma School of Chemical Engineering,who is well known for making the weirdest ❗ questions in exam, his one and only final exam question in May 1997 for his Momentum, Heat and Mass Transfer II class was: “Is Hell exothermic (gives off heat) or endothermic (absorbs heat)? Support your answer with a proof” 😕
1)An engineer, a physicist and a mathematician are staying in a hotel.
The engineer wakes up and smells smoke. He goes out into the hallway and sees a fire, so he fills a trash can from his room with water and douses the fire. He goes back to bed.
Later, the physicist wakes up and smells smoke. He opens his door and sees a fire in the hallway. He walks down the hall to a fire hose and after calculating the flame velocity, distance, water pressure, trajectory, etc. extinguishes the fire with ReAd MoRe…
