Amazing experiment using a light bulb and a plasma ball.
 
Plasma globe (Tesla coil) causes the lightbulb to turn on; Tesla did these things in 1890 demonstrating wireless electricity

Tesla coil's electromagnetic field induces an electric current in the mercury vapor in the bulb. This excites the mercury vapor which emits UV (ultra violet, invisible to human eye) light that causes the phosphors on the inside of the lightbulb to absorb this UV light and send out visible light that makes it glow.   The conversion of light from one type (UV) to another (VIS) is called fluorescence, which gave the fluorescent lamp its name.  So instead of the normal way to power the lightbulb, it is being powered by induced currents from the Tesla coil.

I hope more people will consider majoring in or studying science, consciousness, astral travel, math or engineering.  The world would be a better place if more people knew more sciences, since we would find solutions much faster to the challenges we face. :)    Soul travel, science & technology allow for a lot of artistic expression, so one can do art while being an astral projector, geek or nerd. :)

Astral and physical science will allow us to bring what is thought of as sci-fi or magic into the everyday reality, things like curing aging or eternal youth, telepathy, living without eating, teleportation, shapeshifting, physical immortality, world peace as explained in the tech-filled videos at  https://plus.google.com/+AlexP/posts/URSW7eeNhhf (some videos feature the Google Director of Engineering who talks about Physical Immortality often). 

For a really cool astral bilocation experiment and a chance to meet a Billionaire, seehttps://plus.google.com/+AlexP/posts/5C5MbiS8hGn. :)

There is more to reality than our science knows - we are surrounded by many dimensions with beings in them and we have a soul!  :)

#astronomy I miss that #uranus   was in #conjunction with #venus this week !!! It's a good opportunity to find easily Uranus in the evening sky.

#astronomy a beautiful animation about the  (almost) Venus-Earth pentagram  du to the 13-8  orbital resonance between both planets. See also : http://en.wikipedia.org/wiki/Orbital_resonance
 
Venus and the pentagram

Steven Dutch, Natural and Applied Sciences, University of Wisconsin - Green Bay, created a pretty applet: "The (almost) Venus-Earth pentagram."

We can see it at this link>>
https://www.uwgb.edu/dutchs/AstronNotes/Earth-Venus.htm

We attempt to understand the meaning of the word "almost" in that applet.

Read an excerpt from what the author writes:
"In The Da Vinci Code, Dan Brown makes a big deal of the perfect five pointed star that Venus makes in the sky. What actually happens is 13 Venus revolutions equals eight earth years equals five synodic periods, or alignments of the Earth, Venus and the Sun. It's remarkable, but not perfect. On June 8, 2004, for example, Venus passed in front of the Sun, a transit. The next one will occur June 5-6, 2012, not quite eight years later. But the next time the cycle repeats (June 3, 2020) Venus and the Sun will once again be aligned as seen from the Earth, but Venus will miss the Sun. There will not be another transit until 2117."

My post: "If we imagine planets with Fibonacci orbits, do they create Fibonacci symmetries?">>
https://plus.google.com/+annaritaruberto/posts/Us63WykQkMg

The animation you see below, at the right side, is a creation from Matthew Henderson, who gives us this explanation:
"8 Earth years are roughly equal to 13 Venus years, meaning the two planets approximately trace out this pattern with 5-fold symmetry as they orbit the Sun."

#astronomy   incoming images of #Ceres   from #Dawn  spacecraft  ! The shots are showing a mysterious double bright  spot inside a  big crater  of the  Dwarf planet  surface ...
 
Dawn's latest images of Ceres show its bright spot is actually twins!

an animation I made for my course in Fourier analysis illustrating the uncertainty principle which expresses that_ the temporal location of a signal is inversely proportional to its frequency localization_ . Here we draw the graphs of f (t) = g (at) and its Fourier transform F (f) (nu) = (1 / a) * F (g) (nu / a) . By varying "a" we show that the more the signal is localized in time the more  it spreads in frequency and vice versa ...

Bears can run up to 30 m.p.h., so this guy can be thankful he was on a bicycle and not on foot. On the bicycle, he has a chance of outrunning the bear, although I wouldn't want to put it to the test.

Here's a helpful PSA about bear encounters:

Love and War by Moonlight
Image Credit & Copyright: Kevin Bourque

Venus, named for the Roman goddess of love, and Mars, the war god's namesake, came together by moonlight in this lovely skyview, recorded on February 20 from Charleston, South Carolina, USA, planet Earth. Made in twilight with a digital camera, the three second time exposure also records earthshine illuminating the otherwise dark surface of the young crescent Moon. Of course, the Moon has moved on from this much anticipated triple conjunction. Venus still shines in the west though as the evening star, third brightest object in Earth's sky, after the Sun and the Moon itself. Seen here within almost a Moon's width of Venus, much fainter Mars approached even closer on the following evening. But Mars has since been moving slowly away from brilliant Venus, though Mars is still visible too in the western twilight.
