Physics is one of the oldest academic disciplines and, through its inclusion of astronomy, perhaps the oldest. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, and the boundaries of physics are not rigidly defined. New ideas in physics often explain the fundamental mechanisms studied by other sciences and suggest new avenues of research in academic disciplines such as mathematics and philosophy.
Advances in physics often enable advances in new technologies. For example, advances in the understanding of electromagnetism, solid-state physics, and nuclear physics led directly to the development of new products that have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization, and advances in mechanics inspired the development of calculus.
Here are interesting things to know about Physics:
- It’s interesting to know that the literal meaning of the word “Physics” is taken from the Greek saying “knowledge of nature”. It is one of the oldest fields of science that dates back to 650 BC which was discovered by Greeks.
- Modern-day applications like GPS which literally show us the right paths of life is based on a physics formula of E= mc 2. The satellite navigation systems are related to geostationary satellites to pinpoint the locations and data exchange using radio waves. So the theory of relativity helps in the proper working of GPS.
- The astronauts who are at the International Space Station experience the time slowly since both velocity and gravity have an effect on the speed of time. This is why astronauts kind of look younger than us.
- Nature’s way of proving that physics is cool is shown in a way of the Dead Sea which is one such marvel. Known for its density because of the presence of salt in this sea, a person can easily float in the water without drowning. So, you don’t have to be a swimmer to enjoy the Dead Sea.
- Can you believe that everything we see in this universe is only 5% of the whole universe? The rest of the things are simply dark energy and dark matter. This makes us feel so insignificant now!
- Remember all your classes when teachers say “Light travels faster”, well it’s not entirely true. See the speed of light does not always pass through the vacuum and it’s only there that they have a constant speed. When it passes through water, protons travel at around 3 quarters that speed.
- Probably all the lazy people out there must be interested in knowing this that the energy is added to the moving object with increased speed. Since mass and energy are equivalent, then while increasing speed, the object’s mass also increases. As you approach the speed of light, mass tends to increase dramatically. But cars and airplanes don’t fall in this category because the increase in speed is temporary in these things.
- Another interesting fact about Physics is that the famous physicist, Stephen Hawking who proposed the existence of Blackhole discovered radiation called “Hawking radiation” which makes the black hole glow and gives off light across the whole spectrum.
- Don’t get surprised that much. Physics has all the answers. Based on the formula of resistance, the body’s electrons repel the objects similarly when we touch the screen of phone. The current circuit is broken, potential drop at the point you touch and sensed by a sensor, implementing required action.
- Atoms are made of protons, neutrons, and electrons along with empty space. So if we gather all the humanity in one place and remove all the empty spaces from the atom, it would fit in a small sugar cube and that would weigh 5 billion tons because of being extremely dense!
- You would be amazed to know that the passage of time is different for people moving at different velocities. Everyone has their own sense of time. This is one of the astounding physics facts you would come across!
