Albert Einstein greatest theories ?

Einstein was a theoretical physicist who discovered and invented major theories of Physics. 

Some major theories of Albert Einstein are:

Quantum Theory of Light

General Theory of Relativity

Special Theory of Relativity

Photoelectric Effect

Wave-Particle Duality

Brownian Movement

and many more..

Albert Einstein Nobel Prize

On 9 November 1922, the Royal Swedish Academy of Sciences voted to award Albert Einstein the previously reserved 1921 Nobel Prize in Physics for “his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect.”

Photoelectric effect is a phenomena of the ejection of electron from the surface of metal  when it is illuminated with the light of enough frequency (or we can say enough energy).

The concept of the photoelectric effect was first documented in 1887 by Heinrich Hertz and later by Lenard in 1902. But both the observations of the photoelectric effect could not be explained by Maxwell’s electromagnetic wave theory of light.

Einstein resolved this problem using Planck’s revolutionary idea that light was a particle. The energy carried by each particle of light (called quanta or photon) is dependent on the light’s frequency (ν) as shown:

E = hν

h=6.626 x 10^(-34) js.

Conceptually , einstein photoelectric equation is ,

Maximum kinetic energy of the ejected electron = Energy incidented - work function of the metal surface

 (KE)max = E - W

albert einstein brain vs normal brain

Based on photographs of his brain, this study showed that Einstein’s parietal lobes–the top, back parts of the brain–were actually 15% larger than average.

 Two structures, the left angular gyrus and supermarginal gyrus, were particularly enlarged. 

These areas, while known to have little to do with IQ, are linked to mathematical ability, visuospatial cognition and become highly active when making unusual associations on tests of creativity.

 The researchers concluded this was likely the reason Einstein could perform the conceptual gymnastics needed to think about time and space with such imagery and abstraction.

source of the information

It's important to note, however, that brain structure alone cannot fully explain Einstein's exceptional intelligence. Many factors, including genetics, environment, education, and personal experiences, likely contributed to his remarkable cognitive abilities. Furthermore, intelligence is a complex and multifaceted trait, and it's difficult to attribute it to any one specific factor.

(It's about your interest in a domain , find that domain and see you will gonna do wonders in that).

albert einstein brain weight

Einstein's brain weighed only 1,230 grams, which is less than the average adult male brain (about 1,400 grams). 

 The authors also reported that the thickness of Einstein's cerebral cortex (area 9) was thinner than that of five control brains. 

However, the DENSITY of neurons in Einstein's brain was greater. In other words, Einstein was able to pack more neurons in a given area of cortex.

 Is albert einstein brain preserved till now

When Einstein died in 1955 at Princeton Hospital in New Jersey, his brain was removed by a local pathologist named Thomas Harvey, who preserved, photographed, and measured it. 

A colleague of Harvey's cut most of the brain into 240 blocks and mounted them on microscope slides. 

From time to time, he sent the slides to various researchers, although few publications resulted. Harvey, who moved around the United States several times in the course of his career, kept the jar containing what remained of the brain in cardboard box.

 Finally, in 1998, Harvey--who died in 2007--gave the jar to the University Medical Center of Princeton, where it remains today.
