Famous Thinkers
#1: Nikola Tesla
A tesla coil (invented by Nikola Tesla) is a special type of transformer that can generate extermely large voltages, due to a phenomenon known as electronic resonance. Each coil in the video below is capable of creating a '13 foot spark' (i.e. 500,000 volts of electricity)
During a 'spark event', the coil is pulsed on for a few hundred millionths of a second. During this short time, thousands of amps circulate within the primary tank circuit (coil of copper wire in the 'neck' of the coil) and the energy is coupled into the secondary resonator (top 'donut'-shaped ring) through magnetism. Therefore, what appears to be a continuous burst of sparks is actually a specific number of sparks generated per second. By modulating the number of sparks that emit from the coil each second, different tones can be produced by the coils - hence: 'Sweet Home Alabama'
#2 - Charles Darwin
This explains pretty much everything you could ever want to know:
#3 - Alexander Fleming
Famous for discovering penicillin through not cleaning his equipment, and
His discovery of penicilin came in 1928 when he noticed that mould had developed accidentally on a set of culture dishes being used to grow the staphylococci germ. The mould had created a bacteria-free circle around itself. Fleming experimented further and named the active substance penicillin.
It was two other scientists however, Australian Howard Florey and Ernst Chain (a refugee from Nazi Germany) who developed penicillin further so that it could be produced as a drug. At first, supplies of penicilin were very limited, but by the 1940s it was being mass-produced by the American drugs industry
Interestingly staphlococcus is now most widely known as the antibiotic-resistant MRSA (Multidrug-resistant staphlococcus aureus) despite it's original form being the precursor to the development of penicilin, and thus antibiotic development as possible.

#4 - Albert Einstein
This one deserves a slightly larger picture:
There is so much to write about here that it would be impossible to cover it all. As such, here is special relativity:
Imagine a rocket that is launched into space and gains speed. Close to lightspeed, three effects take place in space and time:
• The rocket shrinks in size • Its clocks run slow • Its tail runs toward the future relative to its head These effects seem weird to us, but that is because in 3D your eyes only see half the picture. The full picture is in 4D, and in that 4D world, the rocket rushes through the 4th dimension with lightspeed. Imagine the rocket again, but this time, let us exchange a spatial dimension that we aren't using for time (i.e. keep X and Y as spatial dimensions, but put Time on the Z access). The rocket starts with a positive X and Y reading but a 0 time reading. As it begins to move, it rotates in space and time. It's tail is in the future relative to its head, it shrinks in space and moves to the past as a whole, which slows its clock |
Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independant of the motion of all observers. This is the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.
#5 - Alfred Nobel
Slow motion dynamite explosion
|
The founder of the Nobel Prize - that honours people from all round the world for their accomplishments in physics, chemistry, medicine, literature, and for work towards peace.
He was a Swedish scientist, inventor, entrepreneur, author and pacifist (despite his invention of dynamite and a plethora of other, equally devastating, explosives), and still managed to establish companies and laboritories in more than 20 countries, all over the world. |
