Can you imagine living in a world
without the discoveries made by Albert Einstein? Regarded as the world’s
greatest scientist of all times, his theories on Energy, Gravity, Matter, Space
and time paved way for significant advances in these fields. Let’s take a look
at some of his theories on modern science.
Albert Einstein and NASA - In the year 1905, Albert Einstein’s
theories about light, gravity, motion, mass and energy began a new era of
science. These led to the big-bang theory which focuses on how the universe was
born while also leading to concepts like black holes and dark energy. Many of
current space science projects are built on Einstein’s famous work for NASA “Beyond
Einstein” research programme.
Brownian motion – This could by far be the biggest of Einstein
discoveries, where his observation of the zigzag movement of particles in
suspension, helped in proving the existence of atoms as well as molecules.
Einstein’s theory helped in significant statistical predictions about a motion
of particles which are randomly distributed in a fluid.
The Sky is Blue – Albert Einstein finally settled the case, “Why Sky is
Blue?” in 1911 after calculating the detailed formula for the scattering of
light from molecules and this was proved right with an experiment.
Theory of Relativity and E=mc² - This theory helped explain that
time and motion are relative to absorbers, as long as the speed of light is
constant while natural laws are the same throughout the universe. Einstein
proposed that gravity is a curved field which is found in the space-time
continuum that is created by the existence of mass. This theory changed much in
the way how scientists look at the world and also set the foundation for
several modern inventions, including the nuclear bomb as well as the nuclear
energy.
Einstein Refrigerator – Albert developed a refrigerator
design which used Ammonia, water, butane and required no energy to work, but it
is still one of the least known inventions by the scientist. Considering the
energy demands, companies throughout the world might realize the importance of
cooling and refrigeration without the need for consuming more energy, and
develop this concept even further in the near future.
Manhattan Project – Einstein created the Manhattan project which is a
research supported by the US that in 1945, led to the development of the atomic
bomb. However, after learning the destruction which was caused by the atomic
bomb in Japan during World War II, he started campaigning for a ban on nuclear
weaponry.
Quantum
theory of Light – This theory highlighted that light is a
composition of small packets of energy which are called photons and have wave
like properties. In this theory, Einstein also explained the process of
emission of electrons from metals which are stuck by lightning. This was called
the photoelectric effect and the theory later led to the invention of the
modern day Television, which gave technologists a new vision to come up with
devices having screens. The Quantum theory of Light became an important discovery
for several branches of science and Einstein was awarded the Nobel Prize for
Physics in 1921 for the same.
