did you know that a standard LPG Bunsen burned on a Blue flame gives just over .25g of Downwards thrust, and only .06g of thrust on a yellow flame.

Neat. TY. Did you know that overcooked meats have more heterocyclic amines.

The heterocyclic amines are formed during high temperature cooking.

 

These are proving to be able to give Cancer now. The heterocyclic amines have been shown to cause mammary gland tumors in laboratory rats. Hence avoid high heat BBQ.

Homing pigeons have a harder time getting home when their right nostril is blocked. This is a case of olfactory lateralization.

A few minutes ago walking on a path near my woodland home I found quite a handsome banana slug crawling across the path. I went and got a ruler and found that the slug was 182 mm long (a little more than 7 inches) and it was cooking along at an average of 162 mm/min (6.4 in/min). This translates to 9720 mm/hr (383 in/hr) or 0.00972 km/hr (0.006 mph). With an N of one and three timed distance measurements this should be considered a pilot study on banana slug speed. I don’t know why he/she was crossing the road or any other particulars.

 

Banana slugs, presumably Ariolimax californicus in my area, are the largest slug in the Americas and while mine was in the average range, they can be much larger, but less than one foot. They are quite attractive with a yellow-green color, similar to a banana, but with large dark spots in different patterns on individuals. Check out the Banana Slug Derby race at Prairie Creek Redwoods State Park on the Northern California coast. Here is a story about the races- http://www.highlightskids.com/Science/Stories/SS0800_slugRace.asp

If you repeatedly recall information you better remember the topic being recalled, a good way to help with that can be by making mind maps in your head and when you think of one part of the web slowly everything in that web pops into your memory effectively helping you to know more and make connections. Takes some time to get use to doing subconsciously but it works.
