Five Interesting Things

(The picture is of lightspeed)

The facts are:

1.) Einstein's Brain 
Einstein's autopsy was conducted in a lab at Princeton Hospital by pathologist Thomas Stoltz Harvey shortly after his death in 1955. Harvey removed and weighed the brain and then brought it to a lab at the University of Pennsylvania where he dissected Einstein's brain into several pieces; some of the pieces he kept to himself while others were given to leading pathologists. He claimed he hoped that cytoarchitectonics would reveal useful information. Harvey injected 11.4% formalin through the internal carotid arteries and afterwards suspended the intact brain in 10% formalin. Harvey photographed the brain from many angles. He then dissected it into about 240 blocks (each about 1 cm3) and encased the segments in a plastic-like material called collodion. Harvey also removed Einstein's eyes, and gave them to Henry Abrams, Einstein's eye doctor.

2.) Da Vinci's Inventions 
Da Vinci's designs were spectacularly ahead of his time. If they had actually been built, they might have revolutionized the history of technology. What were some of his most imaginative sketches, designs and inventions?
1.) The Parachute
2.) The Machine Gun
3.) The Diving Suit 
4.) The Armored Tank
5.) A Self-Propelled Cart
6.) The Aerial Screw (Helicopter)
7.) Ornithopter (Aeroplane)*
*It's wings were designed to flap.

3.) Life (as we know it)
Number of possible planets in our galaxy that might harbor life (as we know it) forming the molecule DNA  : 10, 000,000,000,000,000,000 (1 in a million stars) the first such life-like planet is (Kepler 22B) 600 light years away. 
What we are made of : hydrogen helium & carbon "Every molecule, every element in your body was generated sometime in the distant past by processes within stars."
These elements are abundant throughout the know universe. 

4.) Proof of Life (after death)
In physics, the law of conservation of energy states that the total energy of an isolated system cannot change—it is said to be conserved over time. Energy can be neither created nor destroyed, but can change form, for instance chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite.
5.) Top speed 
The speed of light in mph (miles per hour) is 670,616,629 mph.
The top (man-made) speed : On 
Oct 9, 2013 At 3:21 p.m. (EDT), NASA'S Juno Mission spacecraft will slingshot around Earth towards Jupiter, accelerating to 25 miles per second* along the way (fifty times faster than a speeding bullet) becoming the fastest man-made object in history. A .50-caliber bullet travels at about half a mile a second, by contrast -- nowhere near the blistering speed of Juno. In comparison to the speed of light = in a vacuum ; 186,282 miles per second. We have along way to go for warp speed.
