Do you know how to differentiate a hard-boiled egg from a raw egg? Watch the fascinating demonstration below:
There are 3 simple steps to test your egg:
Spin the egg
Stop the egg
Watch the egg
A hard-boiled egg will stop spinning after you stop it. A raw egg continues to spin even after you stop it. That’s because the egg yolk inside the raw egg is still spinning and swirling inside the raw egg’s shell.
Videography back story
So I recorded the actual demonstration a day earlier than the face-to-face video. I had to make sure the experiment worked first. Hey, I had to boil 2 eggs! The stove and I aren’t exactly close friends. Huh, why 2 eggs? Well, 1 egg was for backup, in case the original hard-boiled egg didn’t work out.
This meant I had 3 eggs to eat. Wait, where did the 3rd egg come from? Well, I scrambled the raw egg contents into some noodles. No food wasting, ok? So 2 hard-boiled eggs, and 1 scrambled egg with noodles. I do not want to see another egg in the immediate future…
That actual demonstration video was recorded on my digital camera, which is a little dated according to current standards. I can only get a 640 by 480 resolution, which is a far cry from the 1280 by 720 HD resolution I needed. Buuut, you use what you can get…
“Better educational outcomes are a strong predictor for future economic growth,” said OECD Secretary-General Angel Gurría. “While national income and educational achievement are still related, PISA shows that two countries with similar levels of prosperity can produce very different results. This shows that an image of a world divided neatly into rich and well-educated countries and poor and badly-educated countries is now out of date.”
Wealth and level of education does not come hand in hand. You still have to work for it.
The best school systems were the most equitable – students do well regardless of their socio-economic background. But schools that select students based on ability early show the greatest differences in performance by socio-economic background.
I’m a bit cautious of this one. Skill honing at an early stage assumes that whatever a student is good at has already manifested itself. It’s a reasonable assumption. It’s only dangerous if the skill specialisation is to the exclusion of all else (or even “many” else). It gets worse if the student don’t like his “special” ability, and also has aptitude in another area that he likes. But the student is already shuffled into Box A for the first skill.
