Mars: More water and more questions

NASA announced the week that Curiosity has backtracked to a formation it passed a few months ago to take a closer look at deposits of silica.C00002

Silica is silicon dioxide, a mineral which makes up 26% of the earth’s crust by weight. Silica based minerals include quartz, opal and tridymite. Tridymite is rare on earth and is usually found in areas which have experienced magma flow. NASA scientists were surprised to find it in the silica deposits examined by Curiosity.

Why is all this important? Continue reading “Mars: More water and more questions”

AI: Learning all the time

R00002ThinkingRobotA team led by Brenden Lake at the Center for Data Science at New York University has developed a program which allows artificial intelligence to learn as humans learn.

To date AI learning is accomplished by processing incredibly large amounts of data.

In a research article published in Science, Lake and his team describe a model which learns “rich concepts” through a probability model built on Bayesian logic. Continue reading “AI: Learning all the time”

Pluto in false color

Unless a faster form of propulsion is perfected and adopted, it will be decades before another mission visits Pluto. So we will have to be content with the dribbling out of data from NASA which New Horizons captured on its one day fly by last July.

This false color image was created by NASA.Pluto001

Fun to look at. Sad to think that our present technology is so limited that we won’t be returning to Pluto anytime soon.
