"Head over Heels" is a song by the British New Wave band Tears for Fears. It was the band's tenth single release in the United Kingdom (the fourth taken from their second LP Songs from the Big Chair) and eighth UK Top 40 hit, peaking at nº12 in July 1985. In the USA, it was the third single from the album and continued the band's run of hits there, peaking at nº3 on the Billboard Hot 100. A limited edition four-leaf clover shaped picture disc was issued for the single's release in the UK.
"Head over Heels" had been developed nearly two years prior as part of a segue with the song "Broken", which was previously a stand alone B-side to the 1983 "Pale Shelter" single. As the two songs share the same piano/synth motif, "Head over Heels" eventually came to be sandwiched in between two bookend parts of "Broken" in live performances. This placement carried over to the final track listing of the Big Chair LP, with a studio recording of "Broken" preceding "Head Over Heels" and a live reprise of "Broken" following it.
The song features Roland Orzabal on lead vocals.

The definitive answer about the direction water swirls in two hemispheres
Sync the videos yourself: http://toiletswirl.com

For the record Destin and I repeated the experiment 3-4 times each in each hemisphere and got the same results every time.

The idea that water going down a drain or flushed down a toilet swirls in opposite directions in the Northern and Southern Hemispheres has a long history. But few have ever done the experiment. Destin from Smarter Every Day and I performed identical experiments in the Northern and Southern hemispheres. What we found is the direction of water swirl in a toilet, sink, or bathtub is determined by other sources of angular momentum. However if the body of water is big enough, e.g. a kiddy pool, and left still for long enough (at least 24 hours), then the Coriolis effect is observable with water swirling counterclockwise in the Northern hemisphere and clockwise in the Southern hemisphere.

Gordon McGladdery did all of the sound design for the video. We used two songs from other artists (licensed of course). Derek split the first one up so it fades from video to video, and Gordon split the instruments up on the second one. There are violins on one video and percussion on the other for example. It's really neat.

The neat earth animation at the beginning and the synchronizing timer was made by http://eisenfeuer.com/. He also made still images of the earth from the top and the bottom.

Año: 1979
Album: From The Full Moon Story (Daichi)
Autor: Kitaro
Genero: New Age

Himekami, aka Himekami Sensation ((姫神せんせいしょん) was the musical project of late electronic composer and musician Yoshiaki Hoshi. The j-card and contents of this tape highlight the context of the new age music craze, with a catalog of other Higher Octave releases and a postcard to send to the label for more info.

Moonwater was an album that saw an audience wider than that of his native Japan, seeing distribution in the US via Higher Octave Music.

This album exemplifies the new age electronic style he was best known for, new age meets traditional music with unabashed synth timbres and instrumentation. It was a departure from his synthpop and electro-pop albums earlier in his career, which sounded more like YMO than say, his new age peer Kitaro.

Himekami was quite prolific, releasing dozens of albums and and having work appear in various film, TV and VG soundtracks. Although a solo moniker he worked with his wife Etsuko and performed with a band live, a band that continued to perform and record after his death in 2004 under the direction of his son Yoshiki.

Oddball (at least for this particular record) Italo-esque disco track produced by Hans Peter Ströer (of Ströer Bros./Ströer Duo). Stuttgart Germany Private Press record commissioned by dance teacher Ray Lynch, 'Let's Jazz Dance with Ray Lynch', 1982

Longyearbyen on Svalbard is the northernmost settlement with over 1000 residents

Come take a walk with me around Longyearbyen, the largest town on the Norwegian islands of Svalbard.

Parts of it look familiar, but make no mistake, this place is different.

At 78 degrees North, it lies just 800 miles or 1300 kilometres from the North Pole. And with over 2,000 permanent inhabitants it is the Northernmost real town on Earth.

There are only 50km of road, including the small streets between houses, so people get around the island mainly on snowmobile.

In fact there are more registered snowmobiles than residents.

Anyone leaving town is required to travel with a gun and someone who knows how to use it because the islands are also home to polar bears.

The average daytime high is below freezing for all but four months of the year, and from the end of October to mid-February the sun doesn’t rise at all. This is the long polar night.

Living here is tough. This past December an avalanche in town destroyed 10 homes, which used to be here, killing two people.

So how did this cold, remote, ice-covered archipelago come to be inhabited?

The hills around town are rich in coal deposits that have been mined for over 100 years.

The coal was transported to the port via a series of aerial tramways some of which remain today, though they are no longer operational.

Coal is a reminder that Svalbard was not always an Arctic ice world. 360 million years ago it was actually in the tropics North of the equator. A swampy area, it was covered with the precursors to modern ferns, which were much larger than they are today, reaching 10-30 metres in height.

This vegetation was then covered in mud and sand and submerged under the sea. Over time it turned into the coal deposits that in the 20th century brought miners from Norway, Russia, and the US.

Most of the coal mines have now closed and the economy is gradually shifting towards tourism, education and research.

Tourists take trips on snowmobiles and dog sleds.

There is a university centre in Svalbard, which offers semester courses in biology, physics and geology.

And up on the side of a mountain is the Svalbard Global seed vault… but that’s a story for another time.

The locals tell me that interest in the region from different nations is increasing.

As the globe warms and Arctic ice shrinks, trade routes are opening up across the North. And Svalbard is strategically placed between North America, Asia and Europe.

One day in the future Svalbard may no longer be as cold or remote as it once was.

But for now it is a reminder of how through our ingenuity people can live in the most inhospitable of places.

A planet has been predicted to orbit the sun with a period of 10,000 years, a mass 5x that of Earth on a highly elliptical and inclined orbit. What evidence supports the existence of such a strange object at the edge of our solar system?

Huge thanks to:
Prof. Konstantin Batygin, Caltech
Prof. David Jewitt, UCLA

I had heard about Planet 9 for a long time but I wondered what sort of evidence could support the bold claim: a planet at the very limits of our ability to detect one, so far out that its period is over 60 times that of Neptune. The planet 9 hypothesis helps explain clustering of orbits of distant Kuiper belt objects. It also explains how some of these objects have highly inclined orbits - up to 90 degrees relative to the plane of the solar system. Some are orbiting in reverse. Plus their orbits are removed from the orbit of Neptune, the logical option for a body that could have ejected them out so far. The fact that the perihelion is so far out suggests another source of gravity was essential for their peculiar orbits.

Below is a further discussion by Henry Reich that I think helps summarize why axes 1 and 3 are generally stable while axis 2 is not:

In general, you might imagine that because the object can rotate in a bunch of different directions, the components of energy and momentum could be free to change while keeping the total momentum constant.

However, in the case of axis 1, the kinetic energy is the highest possible for a given angular momentum, and in the case of axis 3, the kinetic energy is the lowest possible for a given angular momentum (which can be easily shown from conservation of energy and momentum equations, and is also fairly intuitive from the fact that kinetic energy is proportional to velocity squared, while momentum is proportional to velocity - so in the case of axis 1, the smaller masses will have to be spinning faster for a given momentum, and will thus have more energy, and vice versa for axis 3 where all the masses are spinning: the energy will be lowest). In fact, this is a strict inequality - if the energy is highest possible, there are no other possible combinations of momenta other than L2=L3=0, and vice versa for if the energy is the lowest possible.

Because of this, in the case of axis 1 the energy is so high that there simply aren't any other possible combinations of angular momentum components L1, L2 and L3 - the object would have to lose energy in order to spin differently. And in the case of axis 3, the energy is so low that there likewise is no way for the object to be rotating other than purely around axis 3 - it would have to gain energy. However, there's no such constraint for axis 2, since the energy is somewhere in between the min and max possible. This, together with the centrifugal effects, means that the components of momentum DO change.

In summary, ultraviolet light interacts differently with matter for a number of reasons:
1. Some pigments selectively absorb UV so they may appear white in the visible but dark in the UV. The pigments usually dissipate the UV energy as heat, though the breaking of bonds can also occur.
2. Fluorescent molecules absorb UV light and re-radiate that energy as visible light. This makes them look dark in the UV but glowing under black light.
3. Ultraviolet light scatters more than visible light because the wavelength is shorter and Raleigh scattering is proportional to the reciprocal of wavelength to the power of four.

A few years ago I made a documentary about uranium, radioactivity and radiation. I always thought of the characters in our story as the scientists and maybe the uranium nucleus itself. It was only through making the documentary that I realized the real hero of the story is the neutron. Without a neutral nuclear particle, it would be virtually impossible to release the energy from the nucleus. But with it, and the idea of a chain reaction, nuclear energy went from science fiction to reality. That is something I had not grasped as clearly before and it motivated me to make this video.
