I'm taking a university course next semester that'll use determinants. So no worries-- I'm seeing both approaches.Buffu said:He hates determinants. Think twice before using that book.
Melvin Schwartz's "Principles of Electrodynamics" -Demystifier said:What book are you reading now, or have been reading recently? Only STEM (science, technology, engineering and mathematics) books are counted.
Well one more year. It was July 1969.ElectricRay said:Just started on Apollo 13 by Jim Lovell and Jeffrey Kluger. What an exciting time it must have been but the US did it even when it got wrong.
I hope in the near future mankind will start to travell again the the Moon and other placesbin our solar system. This year it will be 60 years Armstrong made his famous step on the Moon.

True! But the cognitive abilities of birds vary in specialty. For an example, Crows understand the concept of metatools. That is, if they have a stick that is too short to grab a prize, they understand that they can use the short stick to get a longer stick which would ultimately get them what they're after. Pigeons can't do this, but their spatial intelligence in way up there. You can put them in a box, drive hundreds of miles away, and they'll fly back home with amazing accuracy. Another bird, and I don't remember the name, remembers where it stored over 600 items for as long as 6 months. Pretty nuts!vanhees71 said:But it depends somewhat on the bird!
