There are radiotelescopes also, like Arrecibo (300m) or Effelsberg (100m).
Of course, you don't have the light gathering capacity of a 130m telescope, but you have the spatial resolution of a130m telescope.
Siever is a SI unit.
i was wrong, that's between Sivert and Gray units.
I think that is only with gamma radiation. for other types of radiation you have to apply a conversion factor, since sievert doesn't really measure energy, but damage to tissues. For alphas for example, the factor is 20.

Bah, they just need to leak some info about PayPal now, to thank them.
Nah, I just think it is just the way they see things in Microsoft. When an OS is stable and works reliably, then it is at the end of its life cycle (like Windows XP).
You can also drink beer in German theaters.
Only if it converts all the energy into heat.
a 200w microwave transmitter doesn't heat by 200W, but ( 200W - transmitted power ).
All politicians come from American parents? That can explain why we are doing so bad in the rest of the world...
That's the problem of having a poorly named country (United States of America), then you have to invent things like "The Americas", to distinguish it from the continent. There are other United States also, like Brazil and Mexico.
And then you have the problem that they think that only them are "Americans", that's why in so many countries (including, for example, Spain) they are called Gringos or Yankees. USian defines the situation better, but somehow they don't like to be called that way.
And even though wikipedia is not the most reliable site, when you search for "America", the result you get is:
America usually refers to either:
* The Americas
* The United States of America
So even though there is no continent called America, there is also no country called that way either.
USians, not Americans.
