Cloud Chambers: Visualizing Radiation 

The cloud chamber, also known as the Wilson chamber, is a particle detector used for detecting ionizing radiation.

In its most basic form, a cloud chamber is a sealed environment containing a supersaturated vapor of water or alcohol. When a charged particle (for example, an alpha or beta particle) interacts with the mixture, the fluid is ionized. The resulting ions act as condensation nuclei, around which a mist will form (because the mixture is on the point of condensation). 

The high energies of alpha and beta particles mean that a trail is left, due to many ions being produced along the path of the charged particle. These tracks have distinctive shapes, for example, an alpha particle’s track is broad and shows more evidence of deflection by collisions, while an electron’s is thinner and straight. -(x)

Hey Tumblr fam, I need some help

I created this anti-hangover popsicle, have tested the crap out of it, and yes it works amazing. My friends love it, but I’m struggling with sales. Just being honest here. 

Anyway, if you get a chance please check out our website Lushzie.com I would love your feedback.

So for all my tumblr fam we are offering the popsicle that will literally end your hangovers for just $1 (to cover shipping) use code “TUMBLRFAM” at checkout. 

The popsicle contains coconut water, electrolytes, and nutrients to protect your liver and help your body metabolize alcohol faster preventing a hangover.

The Strangest Eclipse Fact Of All: The Moon’s Shadow Isn’t A Circle

“These imperfections along the edge of the lunar limb don’t just reflect peaks and valleys on the Moon’s surface, but result in sharp edges and corners appearing on the Moon’s shadow as well. Thanks to incredibly accurate mapping of elevation of the entire lunar surface by NASA’s Lunar Reconnaissance Orbiter, we know exactly what the profile of the Moon looks like. Combine that information with the Earth-Moon-Sun orbit, and we can derive what irregularities will be present during the August 21st, 2017 (or any) solar eclipse, when the Moon’s shadow passes across Earth’s surface.”

The Moon is spherical, and so its shadow should be a circle by simple geometry, right? Only, if we view it when it strikes Earth, it’s not even close to a circle. It’s stretched into an ellipse, and further complicated by irregular, sharp edges and corners. Why would it appear that way? As it turns out, three factors combine to get us there. The first is the fact that Earth is a sphere, not a disk, so any shadow falling on it gets stretched. The second is that the Moon’s sharp peaks, valleys and craters mean that its shadow gets irregularly distorted in a way that changes as its orbit continues. And the third is that Earth isn’t smooth, but exhibits significant changes in elevation and terrain.

Add them all up, and you’ve got the incredibly bizarre and ever-changing shape of the Moon’s shadow. Come see what the eclipse of August 21, 2017 will hold!

This Black History Month, let’s celebrate the first African-American woman who traveled in space.

Let’s celebrate black people, who made history! This is so important to know that some of us didn’t give up and were strong enough to achieve something great like this. These stories are inspirational , but we don’t see them in our history books. Even though she was told women can’t go into space, she never stopped believing in her dreams. 

“As a little girl, I was excited, and people kept trying to explain to me why women couldn’t go into space,” Jemison said, according to the university’s student newspaper, The Plainsman. “I always thought they were full of it.”

She’s the role model for every black kid, who has big dreams! She is a living proof everything’s possible!

Magnetic hard drives go atomic

Physicists demonstrate the first single-atom magnetic storage.

Chop a magnet in two, and it becomes two smaller magnets. Slice again to make four. But the smaller magnets get, the more unstable they become; their magnetic fields tend to flip polarity from one moment to the next. Now, however, physicists have managed to create a stable magnet from a single atom.

The team, who published their work in Nature on 8 March1, used their single-atom magnets to make an atomic hard drive. The rewritable device, made from 2 such magnets, is able to store just 2 bits of data, but scaled-up systems could increase hard-drive storage density by 1,000 times, says Fabian Natterer, a physicist at the Swiss Federal Institute of Technology (EPFL) in Lausanne, and author of the paper.

“It’s a landmark achievement,” says Sander Otte, a physicist at Delft University of Technology in the Netherlands. “Finally, magnetic stability has been demonstrated undeniably in a single atom.”

Flying to New Heights With the Magnetospheric Multiscale Mission

A mission studying Earth’s magnetic field by flying four identical spacecraft is headed into new territory. 

The Magnetospheric Multiscale mission, or MMS, has been studying the magnetic field on the side of Earth facing the sun, the day side – but now we’re focusing on something else. On February 9, MMS started the three-month-long process of shifting to a new orbit. 

One key thing MMS studies is magnetic reconnection – a process that occurs when magnetic fields collide and re-align explosively into new positions. The new orbit will allow MMS to study reconnection on the night side of the Earth, farther from the sun.

Magnetic reconnection on the night side of Earth is thought to be responsible for causing the northern and southern lights.  

To study the interesting regions of Earth’s magnetic field on the night side, the four MMS spacecraft are being boosted into an orbit that takes them farther from Earth than ever before. Once it reaches its final orbit, MMS will shatter its previous Guinness World Record for highest altitude fix of a GPS.

To save on fuel, the orbit is slowly adjusted over many weeks. The boost to take each spacecraft to its final orbit will happen during the first week of April.

On April 19, each spacecraft will be boosted again to raise its closest approach to Earth, called perigee. Without this step, the spacecraft would be way too close for comfort – and would actually reenter Earth’s atmosphere next winter! 

The four MMS spacecraft usually fly really close together – only four miles between them – in a special pyramid formation called a tetrahedral, which allows us to examine the magnetic environment in three dimensions.

But during orbit adjustments, the pyramid shape is broken up to make sure the spacecraft have plenty of room to maneuver. Once MMS reaches its new orbit in May, the spacecraft will be realigned into their tetrahedral formation and ready to do more 3D magnetic science.
