Black holes, which were predicted by maths (solution of Einstein's field equations) before they were discovered in nature, are singularities - points where the familiar laws of physics cease to apply. They are surrounded, however, by surfaces known as . Anything crossing the event horizon is swallowed for ever. If you are a student of physics then you definitely know, this is a problem because the second law of (the strictest of nature’s constraints) says that , a form of disorder, must always increase. But if high-entropy systems could be sucked into nothingness by black holes, that would not be the case. Then an English man came to the scene and solved this problem by showing that black holes themselves had entropy, and that the more they swallowed, the greater it got. This in turn implied that black holes had a , and thus must give off . That English man is our "scientist of the day" today (Second Article of the Day).

Did you know?? Stephen Hawking was born January 8, 1942, on the 300th anniversary of 's death and died today, March 14th, on the anniversary of 's birth. (After all, Time is relative)

Hawking's scientific works included a collaboration with on gravitational theorems in the framework of , and the theoretical prediction that black holes radiation, often called Hawking radiation. Initially, Hawking radiation was controversial. By the late 1970s and following the publication of further research, the discovery was widely accepted as a major breakthrough in theoretical physics. Hawking was the first to set out a theory of cosmology explained by a of the general theory of and . He was a vigorous supporter of the interpretation of quantum mechanics.

Modernity stands on the shoulders of . Their historical foundations support and inspire our today. In 19th century, in Germany, there was such a historical man, who had the ability to integrate book knowledge with fundamental bench . That man is our "scientist of the day" today.

(Scientist of the Day - 22 February)

In 1877, Hertz enrolled at the polytechnic in , where he encouraged by his teachers, to study the original works of famous physicists such as Isaac , Gottfried , Joseph , and Pierre-Simon . But he was dissatisfied with the level of physics education in Munich, so he moved to Berlin where he studied under Hermann von & .

In 1883, he began his studies of ’s electromagnetic theory...

The task is ... not so much to see what no one has yet seen; but to think what nobody has yet thought, about that which everybody sees.

The concept of photons running with stopped clocks is something that is pulled straight out of relativity; the faster you’re moving, the slower your onboard clocks are moving, and the closer to the speed of light you’re operating, the more sluggish they get. Once you reach the speed of light, your clock runs infinitely slow - for practical purposes, we can say that time doesn't flow for the photon. As with all things relativity, this isn’t an absolute statement- light still has a finite speed, and we can observe light taking fixed amounts of time to traverse large distances.

When light goes zipping around our Universe, it is physically moving through space at a speed of 186,000 miles every second. But if you could affix a clock to it, an observer that’s not moving at the speed of light would not see the clock moving forwards the way their own clocks do. A hypothetical person moving at the speed of light wouldn’t notice anything weird with their clock, but what they might notice is that the Universe is full of things to smash into.

No matter how fast you’re going, if there’s something in front of you, and you can’t dodge it, you will hit it. This is as true for humans as it is for light, and light is even less capable of dodging an oncoming object than we humans are. Light always travels in locally straight lines - the only way to bend light is to make a curve in the shape of space. A photon will then follow that curve, but there’s no onboard navigation.

Kirchhoff’s Law was published in the year 1845 by the physicist Gustav Kirchhoff.

Kirchhoff’s Current Law:
The algebraic sum of all incoming current and outgoing current in a node is equal to zero.

Kirchhoff’s Voltage Law:
The algebraic sum of all voltages across any closed loop in a circuit is equal to zero.
