Caustics

The envelope of light rays reflected or refracted by a curved surface is called a Caustic.

All the light rays incident on the caustic surface are tangent to it.

The next time you take a sip from your coffee mug, be sure to take a look at its soul that it benevolently exhibits.

In the case of a circle, the caustic shape/curve formed is the cardioid.

Even water produces some really interesting caustic patterns

and so does wine in a glass.

Some of the images that have portrayed in the post have been made using computer graphic rendering systems. They trace the possible paths of light beam, accounting for refraction and reflection.

Have a great day!

What Are The Most Energetic Particles In The Universe?

“The fastest protons — the ones just at the GZK cutoff — move at 299,792,457.999999999999918 meters-per-second, or if you raced a photon and one of these protons to the Andromeda galaxy and back, the photon would arrive a measly six seconds sooner than the proton would… after a journey of more than five million years! But these ultra-high-energy cosmic rays don’t come from Andromeda (we believe); they come from active galaxies with supermassive black holes like NGC 1275, which tend to be hundreds of millions or even billions of light years away.”

When it comes to the Universe, you might think that energy really is only limited by rarity: get enough particles accelerated by enough supermassive, super-energetic sources, and it’s only a matter of time (and flux) before you get one that reaches any arbitrary energy threshold. After all, we’ve got no shortage of, say, supermassive black holes at the hearts of active galaxies. And yes, we do find cosmic rays hundreds, thousands or even millions of times the energy that the LHC can achieve. But when we think about the Universe in detail, these cosmic rays aren’t unlimited in their energy, but are rather stopped in their tracks by the most unlikely of sources: the ultra-low-energy cosmic microwave background, left over some 13.8 billion years after the Big Bang.

Come get the full story on the most energetic particles in the Universe, and learn why we have those limits at all!

This Interview With Nikola Tesla From 1899 Reveals His Extraordinary Personality
By The Mind Unleashed

By The Mind Unleashed

Very interesting interview Nikola Tesla and John Smith in which he said: Everything is the Light. In one of its rays is the fate of nations, each nation has its own ray in that great light source, which we see as the Sun. And remember: no one man that existed did not die.

JOURNALIST: Mr. Tesla, you have gained the glory of the man who got involved in the cosmic processes. Who are you, Mr. Tesla?
TESLA: It is a right question, Mr. Smith, and I will try to give you the right answer to it.

JOURNALIST: Some say you’re from the country of Croatia, from the area called Lika, where together with the people are growing trees, rocks and starry sky. They say that your home village is named after the mountain flowers, and that the house, where you were born, is next to the forest and the church.
TESLA: Really, all it true. I’m proud of my Serbian origin and my Croatian homeland.

JOURNALIST: Futurists say that the Twenty-and Twenty First Century was born in head of Nikola Tesla. They celebrate conversely magnetic field and sing hymns to Inductions engine. Their creator was called the hunter who caught the light in his net from the depths of the earth, and the warrior who captured fire from heaven. Father of alternating current will make the Physics and Chemistry dominate half the world. Industry will proclaim him as their supreme saint, a banker for the largest benefactors. In the laboratory of Nikola Tesla for the first time is broken atom. There is created a weapon that causes the earthquake vibrations. There are discovered black cosmic rays. Five races will pray to him in the Temple of the future, because they had taught a great secret that Empedocles elements can be watered with the life forces from the ethers.
TESLA: Yes, these are some of my most important discoveries. I’m a defeated man. I have not accomplished the greatest thing I could.

JOURNALIST: What is it, Mr. Tesla?
TESLA: I wanted to illuminate the whole earth. There is enough electricity to become a second sun. Light would appear around the equator, as a ring around Saturn. Mankind is not ready for the great and good.
