Find all world countries

Lilly is american girl, almost 2 years old. She can barely speak, but she knows locations of all world counties. Please see 'Lilly - the map genius' video here.

Well, that really surprised me, because I can not understand where that little human finds a will to learn that kind of information. May it be the appreciation from her parrents she wants to gain?
Anyways, i thought – well... if 2 years old kid, can learn all world country locations, how long it will take me to learn (;. And, to be honest, it took me two evenings. I was very close to do it on one evening. But even in the begining of second, there was some contries i could not locate.
So here is a game where you need to locate world countries. In this video I find all of 20 randomly picked countries, 3 times in a row. Yea, i am at least as smart as Lilly is (;

Left/Right brain conflict

Here is one tricky task called "Left-Right conflict" Look at the chart and say the COLOR , not the word. Your right brain tries to say the color, but your left brain insists on reading the word.

What is the difference between conjecture and hypothesis?

Similarities. Both of them are statements based on observations, that seem to be true, but have not been proved or disproved jet. Differences . As explained in G.Pólya and L.Bowden book "Mathematical methods in science", difference is in level of credibility that explanation is based on. Hypothesis is testable, and explanation is based on accepted grounds. Conjecture is proposition based on inconclusive grounds, and sometimes can not be fully tested. Another difference is that conjectures, unlike hypothesis, are used in math. Hypothesis usualy are used elsewhere. If conjecture is proven, it becomes a theorem . Still, the border between two terms remains blurry, and terms sometimes are used as synonyms. For example in math there is a conjecture called ' Riemann hypothesis ', which correctly should be called ‘Riemann conjecture’.

What is "impossible triangle"? (In business)

Impossible triangle, in business, is triangle that describes any good or service that is provided by any company. And it states that three values Quality, Speed and Price can not all be combined into one offer. One MUST be sacrificed. Either product will be delivered fast and in good quality, but it will cost more. Either it will be in good quality, cheap, but it will be delivered in ordinary time. Or maybe it will be fast, cheap but the quality will be sacrificed. I heard, from one Harvard's graduate, this is what they learn in first semester, in business school. I think this is what i learned in first week in 'life school'.
