LORDS: BAD TEACHING OF SCIENCE IN EINSTEIN'S WORLD |
http://politics.guardian.co.uk/publicservices/story/0,,1940024,00.html
"Science teaching is in a dangerous decline that is putting Britain's
technological future at risk. Only a complete overhaul of education
policy can rescue the situation, a high-powered House of Lords
committee warns today."
I suspect some Lord bumped into the wisdom "I measure your clock to be
slower than mine and you measure mine to be slower than yours but if
you go and return you will find mine to be faster than yours" that
freshmen should learn by rote very diligently.
Another Lord found a famous textbook where freshmen are taught how to
see through opaque bodies:
http://www.courses.fas.harvard.edu/~phys16/Textbook/ch10.pdf
Problem 7, "Seeing behind the stick", p. 47 (solution on p. 54).
Then the Lords asked: "What remains of students' rationality after such
teaching?" and immediately answered: "Nothing". Hence the conclusion
that teaching of science in Einstein's world is bad.

Views:
"In your reference frame, the stick is shorter than L. Therefore, right
before it hits the wall, you will be able to see a mark on the ruler that is
less than L units from the wall (see Fig. 10.31)."
"But in the stick's frame, the marks on the ruler are closer together.
Therefore, when the wall hits the stick, the closest mark to the wall that
you can see on the ruler is greater than L units"
Q: "Which view is correct (and what is wrong with the incorrect one)?"
Note: that is --or *should be*-- a trick question.
A: "The first reasoning is correct."
So far so good. Then: "Now consider the stick's reference frame. [...] Where
is the wall when the signal reaches the left end?"
Hmm... that was not the question. Both views are correct.
Conclusion: Very nice course. A little glitch (their question doesn't
exactly match their solution), but nothing to complain about.

*****.
The stick is longer, it depends which way the light is going, dumbfuck!

Britain's technological future doesn't exist, Britain can't even make a
car anymore.
The kids are not interested in learning science and math, their parents
don't have jobs in industry, there is no industry.
How to defeat fox hunting laws is the main issue and the greatest
British "scientist" is a fool that needs wheels on the Lucasian Chair.
Why are you worried about a moslem nation? The future is
South Korea, 7 megabytes/second broadband for everyone.

I think that it is sweeping to say Britain's technological future does
not exist. The economic answer is of course simply to pay scientists
more. The market will get the message. The question of 7 meg broadband
is an interesting one. If you have this anyone will be able to learn
Physics, or anything else. Latin is also declining. There is a website
devoted to it.

Your tutor could be anywhere in the world including South Korea. There
would also have to be a revolution in the way ALL subjects were taught.
Why not, for modern languages, go straight into a classroom in France,
Germany or Spain. Even Taiwan if you want to learn Mandarin. Of course
outside Europe the World is round and there will be different time
zones.
Experiments have been done in maths teaching.

We may need to fundamentally rethnk how all subjects are taught.

For them, only, an absolute stagnation of a people does matter, whether,
along a time to an other, some does escape, it is called the human beings
mind a power, a definitely as a matter a fact.
