Multi-tasking – something to ponder A lot of people today think they are “good” at multitasking. They’re wrong. LOTS of science has been done, ALL of the evidence says the same thing. They’re wrong. Here’s one way to show you From Psychology Prof at U. Mich, David E Meyer: Say the letters A-J out loud quickly. Go. Say the numbers 1-10 out loud quickly. Go. Say them both out loud, alternating. A-1, B-2, etc. Go.

Questions about anything Any questions about course? Any questions about astronomy? Any questions about your teacher? Any questions at all…

The Montillation of Traxoline Some review material that you’ve probably seen before… The Montillation of Traxoline It is very important that you learn about traxoline. Traxoline is a new form of zionter. It is montilled in Ceristanna. The Ceristannians gristerlate large amounts of fevon and then brachter it to quasel traxoline. Traxoline may well be one of our most lukized snezlaus in the future because of our zionter lescelidge. (attributed to the insight of Judy Lanier)

Traxoline Comprehension It is very important that you learn about traxoline. Traxoline is a new form of zionter. It is montilled in Ceristanna.
