It's just a ride

The world is like a ride at an amusement park. And when you choose to go on it, you think it's real because that's how powerful our minds are. And the ride goes up and down and round and round. It has thrills and chills and it's very brightly coloured and it's very loud and it's fun, for a while. Some people have been on the ride for a long time, and they begin to question: is this real, or is this just a ride? And other people have remembered, and they come back to us. They say, "Hey, don't worry, don't be afraid ever, because – this is just a ride." And we … kill those people. "Shut him up. We have a lot invested in this ride. Shut him up. Look at my furrows of worry. Look at my big bank account and my family. This just has to be real." It's just a ride. But we always kill those good guys who try and tell us that. But it doesn't matter, because – it's just a ride. And we can change it any time we want. It's only a choice. No effort, no work, no job, no savings and money. A choice, right now, between fear and love. The eyes of fear want you to put bigger locks on your doors, buy guns, close yourself off. The eyes of love instead see all of us as one.

Common People

But still you'll never get it right
'cos when you're laid in bed at night watching roaches climb the wall
If you call your Dad he could stop it all.
You'll never live like common people
You'll never do what common people do
You'll never fail like common people
You'll never watch your life slide out of view, and dance and drink and screw
Because there's nothing else to do.

Europa, oceanul si submarinul

Sci­en­tists hope to send a ro­botic sub­ma­rine in­to oceans that may lurk with­in a moon of Ju­pi­ter, in what could be the first ex­plora­t­ion through li­quid wa­ters on an­oth­er world.
Re­search­ers have long spec­u­lat­ed that un­der the icy shell that en­cases the moon, Eu­ro­pa, liq­uid wa­ter might har­bor prim­i­tive life forms. A Eu­ro­pa mis­sion is still years away, ac­cord­ing to sci­en­tists; but in prepara­t­ion for such an ev­ent, they plan to test a NASA-funded ro­botic probe un­der ice on Earth.
Test­ing will take place next week in Lake Men­do­ta on the cam­pus of the Un­ivers­ity of Wis­con­sin, Mad­i­son, ac­cord­ing to a Feb. 8 an­nounce­ment from the agen­cy. The sub is made to “swim un­teth­ered un­der ice, cre­at­ing three-di­men­sion­al maps of un­derwa­ter en­vi­ron­ments,” the an­nounce­ment said. The ro­bot would al­so “col­lect da­ta on con­di­tions in those en­vi­ron­ments and take sam­ples of mi­cro­bi­al life.” The pro­ject is led by Uni­ver­sity of Illi­nois at Chi­ca­go and NA­SA scientists.

Af­ter the Wis­con­sin tests, re­search­ers said they plan to ship the probe to a per­ma­nently fro­zen lake in Ant­arc­ti­ca for fur­ther tri­als. The ve­hi­cle, called EN­DUR­ANCE (En­vi­ron­men­tally Non-Disturbing Un­der-ice Robotic Ant­arc­tic Ex­plor­er), is a $2.3 mil­lion proj­ect. It’s a fol­low-up to the Deep Phre­at­ic Ther­mal Ex­plor­er, an­oth­er NASA-funded proj­ect that fin­ished un­derwa­ter tests in Mex­i­co in 2007, agen­cy sci­en­tists said. Eu­ro­pa, slightly smaller than Earth’s Moon, is the fourth larg­est of Ju­pi­ter’s at least 16 moons, and is cov­ered with whit­ish and brown ice. Be­neath it, many re­search­ers be­lieve the moon may har­bor the only glob­al ocean of liq­uid wa­ter in our So­lar Sys­tem be­sides Earth’s. Im­ages from NASA’s Gal­i­le­o space­craft have shown ar­eas with si­m­i­lar­i­ties to Earth’s ice-floe cov­ered Arc­tic oceans, sug­gest­ing the ex­ist­ence of wa­ter or warm “s­lushy” ice be­low, ac­cord­ing to Da­vid R. Wil­liams, a sci­ent­ist at the agen­cy’s God­dard Space Flight Cen­ter. Such an ocean could con­ceivably pro­vide a home for liv­ing things.
Eu­ro­pa’s in­te­ri­or is hot­ter than its sur­face, ac­cord­ing to Wil­liam B. McK­in­non, a plan­e­tary sci­ent­ist at Wash­ing­ton Un­ivers­ity in St. Lou­is. This in­ter­nal heat comes from the gravita­t­ional pull of Ju­pi­ter and its oth­er large moons, which stretch Eu­ro­pa’s in­sides in dif­fer­ent di­rec­tions and cre­ate fric­tion. Most of the sat­el­lite is made of rock, ac­cord­ing to McK­in­non.

Re­peat­ed split­ting and shift­ing of the sur­face ice, and dis­rup­tions from be­low, have re­shaped Eu­ro­pa’s sur­face, Mcin­non con­tin­ued. A re­sult is that there are few vis­i­ble im­pact craters, since the shift­ing would have erased these. The sur­face shows shal­low cracks, val­leys, ridges, pits, blis­ters, and icy flows, McK­in­non added, none more than a few hun­dred yards or me­ters high or deep. The Ital­ian as­tron­o­mer Gal­i­le­o discov­ered Eu­ro­pa 1610. Its name is said to have been first sug­gested by his con­tem­po­rary, the Ger­man as­tron­o­mer Kep­ler, who pro­posed nam­ing Ju­pi­ter’s moons af­ter the se­cret mis­tresses of Ju­pi­ter, king of the gods in Greek and Ro­man my­thol­o­gy. Ac­cord­ing to myth, Ju­pi­ter took the form of a bull to ab­duct Eu­ro­pa, a Phoe­ni­cian prin­cess.
