The cosmic rays depicted here can be described as high energy particles like protons or other sub-atomic particles. These particles can come from our Sun (Solar cosmic rays) or other places like supernova explosions or neutron stars and black holes (Galactic cosmic rays). Galactic rays are higher energy than solar rays but Extragalactic cosmic rays, which come from quasars/blazars or the black holes in the center of galaxies, are even higher energy.

The plane of the Earth's orbit projected in all directions forms the reference plane known as the ecliptic. The plane of the ecliptic intersects the celestial sphere along a great circle (black), the same circle on which the Sun seems to move as the Earth orbits it. The intersections of the ecliptic and the equator on the celestial sphere are the vernal and autumnal equinoxes (red), where the Sun seems to cross the celestial equator.

Disquisitiones Arithmeticae (Carl Friedrich Gauss, 1801)

The plane of the Earth's orbit projected in all directions forms the reference plane known as the ecliptic. The celestial equator is the projection of the terrestrial equator out into space. As a result of the Earth's axial tilt, the celestial equator is inclined by 23.4° with respect to the ecliptic plane. The image shows the relations between Earth's axial tilt, rotation axis and plane of orbit.

The pattern formed by the interference and diffraction of coherent light is different for a single and double slit. The single slit intensity envelope is shown by the dashed line and that of the double slit is shown by the solid line. The drawing is not to the same scale as the photographs. The number of bright maxima within the central maximum of the single-slit pattern is influenced by the width of the slit and the separation of the double slits.

One of the greatest mathematical challenges of all time was finding positive integers a,b, and c that could satisfy the equation. Fermat's Last Theorem hypothesized that it could not be done . This hypothesis was not confirmed until over 350 years later, by Andrew Wiles who spent 7 years formulating the proof, which ended up being over 100 pages long.

If you divide 1 by 998,001 (result shown in picture) you get all three-digit numbers from 000 to 999 in order, except for 998... If you divide 1 by 9,801 you get all two-digit numbers from 00 to 99 in order, except for 98... If you divide 1 by 81 you get all one-digit numbers from 0 to 9 in order, except for 8.

The Earth Is Round, and It’s This Big. In 240 B.C. Greek astronomer, geographer, mathematician and librarian Eratosthenes calculates the Earth’s circumference. His data was rough, but he wasn’t far off.
