+ - World most dangerous toy 'Gilbert Atomic Energy Lab' goes on display at museum->

Submitted by hypnosec
hypnosec (2231454) writes "The Gilbert Atomic Energy Lab — dubbed as the world's most dangerous toy — has gone on display at the Ulster Museum in Northern Ireland. The toy has earned the title of most dangerous toy because it includes four types of uranium ore, three sources of radiation, and a Geiger counter that enables parents to measure just how contaminated their child had become. The Gilbert Atomic Energy Lab was only available between 1951 and 1952 and was the most elaborate atomic energy educational kit ever produced. The toy was one of the most costly toy of the time retailing at $50 — said to be equivalent to $400 today."

+ - Interstellar travel was almost possible, 70k years ago...->

Submitted by mrthoughtful
mrthoughtful (466814) writes "According to the bods at the University of Rochester, 70,000 years ago, a recently discovered dim star (Scholz's star) passed through our Oort cloud, in a near collision with Sol only 52,000 AU distant. Although this is still quite a distance, it is far closer than Proxima Centauri's current 266,000 AU, but still a stretch for Voyager I's 125 AU. Still, maybe the best way to engage in interstellar travel is just to wait until the time is right."

Dyson is one of my science heros. cf. https://en.wikipedia.org/wiki/...
He is a notable subversive and a joker. He was once commissioned to write a paper for the US DOD regarding the use of nukes in Vietnam. He is pointing something else out in this paper (already three years old - not news), and it appears the irony is being missed.

Although I personally find the idea of resurrecting an old dish rather 'non-news', Tiros was pretty cool series of satellites. Here is the the first (composite) photo of global weather taken using the infrared cameras on an early Tiros: https://history.nasa.gov/SP-16...

Comment: Should have mixed it with Primer. (Score 2) 254

IMO, Primer sets the bar for time-travel movies, even though it's deliberately ambiguous. It seems that really, the only 'next step' is to bring out many more of the complex paradoxes that something like Primer begins to address.

For instance, what would happen (not used, but implied, in Primer) if one put an (unoccupied) running box (IIRC Primer only uses collapsed boxes) inside a running box? My guess is that it would allow for arbitrary backward time travel (with the Primer provisio that it would be a branched universe)..

This is all sort of Solaris stuff - and like Lem suggests, we would have no ability to communicate with an organism of that order. (John C Lilly points out that we wouldn't be able to communicate meaningfully with Whales, let alone planetary organisms).

And when imagining living beings that are larger than planets, how can we even be able to begin to define them as alive?. Why aren't stars alive in the first place? If not, what makes them not so? Just because their method of reproduction involves their own death - it's just a little bit exotic is all.

There's one huge problem with the notion of proof in physics: You never know when your theory might be superseded. You can't make a generalising statement in physics which is essentially formally proven since there is always a possibility that it would be overtaken by a newer one.

So, your cite from tea is pretty meaningless. A 'proof' of this order is noting less than a revised theory, hence my OP

The MooseTick's comparison to the real estate agents is valid. Not everyone is selling crappy houses because there's demand for good ones too. But quantity above quality principle is still valid here. Why risk losing a contract on a salary negotiation trying to make additional $300 when there's $9000 at stake?

Maybe that's just me, but I could secure a better job by myself than anything offered by recruiters. They usually got me offers which have nothing to do with my desired area which is embedded programming. Then again, it's pretty close to full employment amongst software developers in Germany nowadays.
