Today I Learned: 1) When buying a transilluminator, it can really pay to get the more expensive, brighter one.... A too-dim transilluminator isn't much of a transilluminator at all. 2) ...that space has a minimum temperature of 2.7 Kelvin. 3) The US is phasing out private prisons! I can't believe something so sensible is actually coming out of our government! Seriously, what's going on here?
