Filaments on the Inner Ring of the Helix Nebula

This cropped version of the Helix Nebula (also known as NGC 7293) mosaic shows cometary-filaments embedded along a portion of the inner rim of the nebula’s red and blue gas ring. The Nebula is in the constellation Aquarius at a distance of 650 light-years from Earth. The Helix is one of the nearest planetary nebulae to Earth and it a frequency target of study. Because of its ere stare it is sometimes called the “Eye of God”.

Sketching Sum of Sine:

Image 1: A standing wave (black) depicted as the sum of two propagating waves traveling in opposite directions (red and blue). The red dots represent the wave nodes. Harmonic waves travelling in opposite directions can be represented by the equations below:

y1 = Yo.sin(kx - ωt),  and y2 = Yo.sin(kx + ωt)

So the resultant wave y equation will be the sum of y1 and y2 .By using the trigonometric sum-to-product identity for ‘sin(u) + sin(v)’ to simplify:

 y = Yo.sin(kx - ωt) + Yo.sin(kx + ωt) = 2.Yo.cos(ωt).sin(kx)

Images 3, and 4:  A three-dimensional standing wave on a disk; this is the fundamental mode & A higher harmonic standing wave on a disk with two nodal lines crossing at the center.

Images 5:  A “standing wave” in a stream crossing a sandy beach into the sea by Jim Richardson. In physics, a standing wave is a wave that remains in a constant position. Two opposing waves combine to form a standing wave. This phenomenon can occur because the medium is moving in the opposite direction to the wave, or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions. (See more at: Standing Wave on Wikipedia)

Archimedes was a Greek mathematician, scientist and all-around uber-genius who discovered the laws of the lever, which in playground terms is basically a teeter-totter. The idea of levers and balance inspired Matt Buchanan to enter (and win!) the 2012 Marbles Game Design Contest with a game aptly named Rock Me Archimedes. Combining strategy, skill and a little bit of luck, the game consists of a wooden board that rocks like a teeter totter, a special die and 28 marbles. To win, just be the first player to oh-so-carefully get four marbles to your end of the board without reaching the tipping point, causing it to touch the table.

How to Play: On your turn, either add one of your marbles to the any space in the mid zone, or roll the die and move one or more of your marbles the number of spaces indicated. If either end of the rocker board touches the table, the player who caused it to happen forfeits and the game and his or her opponent wins.

How to Win: Be the first player to get four marbles to your end zone without causing it to touch the table

Gemini 4

The Gemini program was designed as a bridge between the Mercury and Apollo programs, primarily to test equipment and mission procedures in Earth orbit and to train astronauts and ground crews for future Apollo missions. The general objectives of the program included: long duration flights in excess of of the requirements of a lunar landing mission; rendezvous and docking of two vehicles in Earth orbit; the development of operational proficiency of both flight and ground crews; the conduct of experiments in space; extravehicular operations; active control of reentry flight path to achieve a precise landing point; and onboard orbital navigation. Each Gemini mission carried two astronauts into Earth orbit for periods ranging from 5 hours to 14 days. The program consisted of 10 crewed launches, 2 uncrewed launches, and 7 target vehicles, at a total cost of approximately 1,280 million dollars.

Gemini 4 was the second crewed mission of the Gemini series and carried James McDivitt and Edward White on a 4-day, 62-orbit, 98-hr flight from June 3 to June 7, 1965. The mission included the first American spacewalk. The objective of the mission was to test the performance of the astronauts and capsule and to evaluate work procedures, schedules, and flight planning for an extended length of time in space. Secondary objectives included demonstration of extravehicular activity in space, conduct stationkeeping and rendezvous maneuvers, evaluate spacecraft systems, demonstrate the capability to make significant in-plane and out-of-plane maneuvers and use of the maneuvering system as a backup reentry system, and conduct 11 experiments.

Happy birthday to the Hubble Space Telescope. On April 24, 1990, shuttle mission STS-31 saw Discovery launch the telescope successfully into its planned orbit. After some early trouble with mirrors and some daring fix-it missions, Hubble has turned out to be one of the greatest achievements in the history of science. Call that hyperbole if you like, but the more I’ve learned about the Hubble Space Telescope — through the telescope, I should say — the more I stand in awe. (NASA/HubbleSite/APOD)
