Walkabout the Galaxy
lakes on Titan; supermassive black holes; pulsars
Astrophysics and Astronomy | Physics
We go deep on this episode of Walkabout, with new analysis of the lakes on Titan showing the largest may be more than 300 meters deep. In deep space, the long, low rumble of spacetime from interactions of supermassive black holes may have revealed itself in subtle changes in the timing of pulsars. Check it all out, plus find out just how long two shakes of lamb's tail really is. We've got the whole universe covered.
The Band Gap
Are you feeling overwhelmed by the constant din of electrons banging around in the conduction band? Have the once melodious tones of the valance band gotten on your nerves? Take a break from the original electronica music and step into the Band Gap. In this unpopulated energy realm, you'll be free of current, and insulated from the push and pull of electric fields, not to mention, your friends constant hectoring. For calming the mind there's yoga, but for calming subatomic electrical activity there's nothing like the band gap. For best results, use the band gap at low temperatures. The Band Gap, imagination at work (General Electric).
