I recommend "The Theoretical Minimum" books as a good starter to get you through to the level of mathematics needed to be able to read the quantum math and vector/tensor calculus used in field equations. Statistical calculus also.

Once you have these under your belt, comprehending the real physics textbooks and papers will be unlocked.

This stuff is not hard are impenetrable, but the language is if you don't know it. The language isn't hard or impenetrable. E.G. Vector calculus is much simpler that algebra. Just find a good book or teacher that doesn't blind you with procedure over concepts.

My algorithm for buying a new car is:
1) Spend about a year deciding what I want and/or need.
2) Simultaneously, start saving the cash.

It's not like you can't tell when a car is nearing the end of time, relative to whatever your own level of love for car maintenance is.

When the time comes, you know what you want and you've got the cash, which makes the bargaining rather trivial.

Base-10 units are not in any way more correct than base-2 units. They are merely more consistent with the way scientific units are generally used (but less practical, since base-2 units correspond to how data is actually addressed and alligned).

I do not oppose people using base-10 units. I do, however, oppose people redefining well-defened units. The idiotic extra i (KiB, MiB, etc.) should have been inserted in the new (base-10) units, not in the existing units. This creates unnessary ambiguity.

I was referring to the internationally standardized system of units. Not the intrinsic merits of any particular base.

So call it a 'programming' course. Computer science marginally overlaps with programming, but a programming course is not computer science.

While we're at it, we could stop calling Computer Science a science and admit it's applied mathematics with silicon thrown in.

>By the sounds of it the only real damage done by salt is kidney damage and that is if you eat too much of it.

Actually too little salt will kill you. Too much salt (in the normal range of dietary input) has no detectable detrimental effect. A 10 ton block of salt on your head will kill you, providing you're in a suitable strong gravitational field.

Any claim I've seen of salt causing kidney damage has been thoroughly debunked.

The devil finds work for idle circuits to do.
