Don't play games! I know you're reading! That's right, freak. It behooves you nothing to ignore me. Take a good look. Quaff deeply from the trough of future shock. Allow that wooly brain to be stricken with envy. You're reading a work from Member 001, Anime Lover, Evil Genius, and Mad Scientist Extraordinaire. Dr. Praxis

As mad as I am
Even as mad as I am I could not have seen 2020 coming....hmmm maybe their is another mad scientist out there messing about...

The Quantization of Time
We have come a long way from the grand father watches of the 19th centuries, having successfully destroyed the necessity to wear one.
( Courtesy : Smart-phone )
But, thanks to watch lovers around the world, their legacy continues.
Tumblr media
Tell me and I’ll forget,
Show me and I may remember,
and Involve me and I will understand.
In this post we will explore the quartz watches of our day.
But to truly understand what happens in a quartz clock, let’s look at something more pronounced- The Lighter. 
The Quotidian Lighter
Tumblr media
It consists of a small, spring-loaded hammer which, when a button is pressed, hits a Piezoelectric crystal. 
Piezoelectric crystal is one which produces a voltage when pressure is applied to it. This effect is known as the piezo-electric effect.
Upon hitting the Piezoelectric crystal, a huge voltage ( ~ 600 V )is created because of the piezo-electric effect.
Tumblr media
The lighter is wired in such a way that this whole voltage is applied in a small region of air gap between two metallic points.
Due to high voltage generated, the air is ionized and acts as a path for the discharge.
Tumblr media
This electric discharge is the spark which when exposed to the combustible gas from the stove ignites it to produce flame.
Tick, tick, tick -The Quartz Crystal
Inside a quartz clock or watch, the battery sends electricity to the quartz crystal ( a piezoelectric material ) through an electronic circuit.
The quartz crystal oscillates (vibrates back and forth) at a precise frequency: exactly 32768 times each second.
Tumblr media
A Quartz crystal oscillator
These oscillations generate small electrical signals which are ‘divided down’ by the circuit within the watch to the required frequency (usually seconds) and translated into pulses which are sent to the watch display or a motor to move the seconds hand.
Remarkable isn’t it?
Tumblr media
Have a Great Day!

Mad Science Convention ?
I’ve been talking to a few people about conventions and I got the idea of creating a mad science convention. It can bring together mad scientists from around the world to meet and share ideas. We can have a few interesting panels. Even could allow the minions to have smaller panels and talks on topics important to minions. We can show off some of more interesting inventions and even vote for mad scientist of the year and best invention. Ah also can't forget the robot battles. 
Yea every year could be a different theme like robotics, genetics, steam technology and so on. 
Oh and the sale of tesla coils so many coils. Would anyone be interested in this ?

Damn this weather
This weather maybe ruin my newest invention but what is mad science for if not to overcoming nature it self. MUahahahahahaha.

Godzilla didn’t do too well critically at release, I can see why, but it does have it’s good points. The sheer lack of sense of the prime minister floors me every time.

Bunch of old school-style War Propaganda posters. These are all modern interpretations of recruitment/morale posters that the US put out in the late 1930s-early 1940s, when we joined WWII. Although it would be awesome if it happened, I have a hard time picturing the US Government putting out something that says “Kick Their Axis,” no matter how clever it is….

HISTORY OF MODERN SCIENCE: THE 18th CENTURY “MECHANICS” Actually, they all seemed to be interested in just about everything.
Daniel Bernoulli (1700-1782) is best known for his work in fluid mechanics, in particular for his discovery that pressure decreases as flow speed increases – a fact that today keeps carburetors running and fixed-wing planes in the air.
Leonhard Euler (1707-1783), Swiss mathematician and physicist sometimes called “the Galileo of mathematical physics,” did ground-breaking work across many fields. He discovered Euler’s number, e, the second most important constant in physics, after pi.
He also introduced much of modern mathematical terminology and notation, for example, the notion of a mathematical function.  Thus, Euler is justifiably remembered as a mathematician. However, he is also known for his work in mechanics, fluid dynamics, optics, astronomy, and music theory.  [wp]
Joseph Fourier (1768-1830) was a pioneer in theories of heat and vibration. The technique he invented for this work – representing complex waves by adding together simpler waves – is now used everywhere in science and engineering.
Thomas Young (1773-1829) pioneered the “double-slit” experiment: shining a light through two narrow slits, he produced a pattern akin to the one produced by two overlapping water waves. This demonstration of the wave nature of light later became central to quantum mechanics.
Young made notable scientific contributions in the fields of vision, light, solid mechanics, energy, physiology, and language. He also advanced European understanding of ancient Egyptian hieroglyphs (notably, those on the famous Rosetta Stone). [wp]
Carl Friedrich Gauss��/ Gauß (1777-1855), called “the prince of mathematicians” by his contemporaries, is now best remembered for his “normal” (or Gaussian) distributions, which plot how likely things are to vary from average.
A German mathematician and physical scientist, he contributed significantly to many fields - in mathematics: number theory, algebra, statistics, analysis, differential geometry. In physics, he did work in geophysics, electrostatics, astronomy, and optics. [wp]
William Hamilton (1805-1865) reformulated Newtonian mechanics into what is now known as Hamiltonian mechanics. In doing so, he wrote the mathematical language in which modern physics, especially quantum theory, is expressed.
Sir William Rowan Hamilton was an Irish physicist, astronomer, and mathematician, who made important contributions to classical mechanics, optics, and algebra. [wp]
