53% of adults now believe the COVID shots have caused a significant number of unexplained deaths.

54% of adults now believe that there are LEGITIMATE reasons to be concerned about the safety of the shots

The largest known prime number as of October 2023 is 2⁸²⁵⁸⁹⁹³³ –1, which has 24,862,048 digits when written in base 10. It was discovered by a computer volunteered by Patrick Laroche of GIMPS in December 2018. This prime number is so large that it would take more than nine hours to read it out loud.

World's First Particle Accelerator ⚛

The world’s first particle accelerator, the cyclotron, was invented by Ernest O. Lawrence in 1929–1930 at the University of California, Berkeley, and patented in 1932. A cyclotron accelerates charged particles outwards from the center of a flat cylindrical vacuum chamber along a spiral path. The particles are held to a spiral trajectory by a static magnetic field and accelerated by a rapidly varying electric field. Lawrence was awarded the 1939 Nobel Prize in Physics for this invention.

The cyclotron was the first “cyclical” accelerator, meaning that it could accelerate particles many times by making them follow a circular or spiral path. The energy gained by the particles was limited by the maximum electrical potential that could be achieved across the accelerating region. This potential was in turn limited by electrostatic breakdown to a few million volts. In a cyclotron, by contrast, the particles encounter the accelerating region many times by following a spiral path, so the output energy can be many times the energy gained in a single accelerating step.

The cyclotron was the most powerful particle accelerator technology until the 1950s, when it was superseded by the synchrotron. Despite no longer being the highest-energy accelerator, they are still widely used to produce particle beams for nuclear medicine and basic research. As of 2020, close to 1500 cyclotrons were in use worldwide for the production of radionuclides for nuclear medicine. In addition, cyclotrons can be used for particle therapy, where particle beams are directly applied to patients.

Nikola Tesla's prediction of a smartphone, Collier’s magazine interview, 1926:

"When wireless is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole. We shall be able to communicate with one another instantly, irrespective of distance. Not only this, but through television and telephony we shall see and hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles; and the instruments through which we shall be able to do his will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket."

Happy 192nd Birthday to James C. Maxwell, one of the most brilliant minds in the history of science.

James Clerk Maxwell was a Scottish physicist, renowned for his pioneering work in the field of electromagnetism. His most significant contribution was the formulation of the classical theory of electromagnetic radiation, which combined electricity, magnetism, and light into a unified theory.
This was done through the development of Maxwell's equations, a set of partial differential equations that describe how electric and magnetic fields interact. The equations predict the existence of electromagnetic waves, which travel at the speed of light, and were fundamental in confirming that light is a form of electromagnetic radiation.
Beyond electromagnetism, Maxwell made significant contributions to the kinetic theory of gases, with Maxwell-Boltzmann distribution providing insight into the statistical nature of molecular behavior. His work in these areas laid the groundwork for much of modern physics, influencing the development of special relativity and quantum mechanics.
