I've just been playing with the following site

www.wolframalpha.com/

Which i think came on-line today (or yesterday).

I typed in
surface brightness M81

Output: 13.0

I typed in
magnitude star vega and capella

Output:
Vega: +0.03
Capella: +0.08

I couldn't get it to compute a combined magnitude.
I could get a star chart and an enquiry into the temperature of star Vega presented a couple of nice black-body curves.

I entered a search comprising words saturn alt and azimuth and it reported current location from Dublin.

I typed ISS and it presented a map of where it is and when it rises and sets from Dublin.

Then it said it was overloaded and pretended to be HAL from 2001 (seriosly - "Dave, I'm afraid I can not do that").

Could be usefull.

Thants impressive;

I put in 'planck constant' and got back

Input interpretation:
h (Planck constant)
Value:
6.626069x10^-34 J s (joule seconds)

Ah yes, I tried to have a go at this a few days ago but wasn't launched then.
A handy little device.
For the fun of it I put in "warp speed" but all I got back was:

Wolfram|Alpha isn't sure what to do with your input.

I'm not sure what to do with it either to be honest! :-)

Seriously though, it is sensitive to how you type something.
I typed in "light speed" but it came back with the same error message as above.
However, whan I put in "speed of light" it came back with the correct details:

Input interpretation:
c (speed of light)
Value:Show exact value
299 792 km/s (kilometers per second)
2.998x10^8 m/s (meters per second)
1 Planck speed
Comparison:
~~ 2.4 x speed of light in diamond (~~ 1.24x10^8 m/s )
Interpretation:
speed
Basic unit dimensions:
[length] [time]^(-1)
Corresponding quantity:
Slowness from S=1/v:\n | 3.336x10^-9 s/m (seconds per meter)
