If the first condition is the slowest you can't get faster than that. But if the first is faster it might be the only one executed.

Be sure to read to the end and notice that habits are what you need. Those unconscious self perpetuating mechanisms that actually drives most things.

Try playing both sides of say a game of chess. I bet if you do it seriously you can't predict the outcome.

Maybe there is no difference. You said when "difficult" you go verbal. Well language, be it natural or math, is the means by which to think rationally and highly conscious. On the ohther hand creative thinking is more done in &quo

You really shouldn't compare salaries through currency exchange rates. When shopping in Denmark for say 100 DKK you will get aproximately the same in Sweden shopping for 100 SEK.

In fact it is an old test reactor from the 1950ies. What they have done, though, which is still very cool, is use thorium instead of uranium in a conventional nuclear reactor.

Not only due to socialistic ideas. Even big private corporations have a tendency to grow organizational pockets and positions of no real value. If you have worked there you will have noticed them.

It is a tremendously giving exercise. I practically learned programming doing that. Disassembling an entire MSDOS like operating system and then amending it with print spooling, RAM disk, and the ability to run two tasks simultaneously on s

I "see" that m^2 + 2m is almost a square. Just one unit square missing: ---------------- |< m >| | ---------------- | |^| | | | | m*m |m| | | | | |v

The if part is meant to illustrate the idea, that if P is not a perfect square, then (m+1)^2 will give the nearest perfect square.

by jonsen 12y ago
You should factorize as n*10^m where m is even. Then the square root of the 10^m factor will be 10^(m/2), which then gives the order of the full square root.

by jonsen 12y ago
Maybe too OT, but here is another proof P = n * (n＋1) * (n＋2) * (n＋3) = n*(n＋3) * (n＋1)*(n＋2) = (n*n ＋ 3n) * (n*n ＋ 3n ＋ 2) = m * (m＋2) If P has an integer square root, it must be (m＋1) Trying (m＋1) * (m＋1)

Interesting thoughts. Now you set me off for at least half a day of thinking further. By the way, your sibling question already set me off studying reactive programming which I didn't know much about. It seems like reactive programming

So that is what consciousness is, the ability to construct a structured model of the world from disorganized unstructured signals. Well, consciousness is more than that. It is also self awareness. But to make a useful world model the brain

This thread needs an argument for the case where the host picks a door at random. The chance for the host getting the car is of course also 1/3. Then the complement 2/3 chance of the host getting a goat splits the car chance evenl

by jonsen 12y ago
If the host picks randomly, the chances must sum to 2/3, not 1.
869.
by jonsen 12y ago
The most straightforward explanation I've heard is this: The chance is 1/3 the car is behind the door chosen at first. The chance is 0 for the opened door. As the three chances must sum to 1, the last door has a chance of 2/3

I've used it once making a DRAM refresh controller. That was almost forty years ago before DRAMs came with refresh circuitry build in and before you could get dedicated chips for it. I made this 6-state sequencer ABC -> A'B
