Blogger Tyler Cowen reviews and extends his time management tips. He adds three new rules:
“6. Don’t drink alcohol. Don’t take drugs.
7. At any point in your life, do not be watching more than one television show on a regular basis.
8. Don’t feel you have to finish a book or movie if you don’t want to.”
One of my favorite sources for time management advice is Zen Habits. Here is a recent entry.
Here are some ideas from LifeHacker:
Yesterday, I blogged about a mnemonic for learning the quadratic equation. Here is an excellent video that teaches a general mnemonic technique for formula memorization:
Going through some of my notes I rediscovered this mnemonic for the quadratic formula:
From square of b, take 4ac;
Square root extract, and b subtract;
Divide by 2a; you’ve x, hooray!
I am not sure of the origins of this mnemonic. The earliest version I could find was from J. S. Mackay in 1894, but he says the mnemonic was given to him by a member of the Edinburgh Mathematical Society.
Here’s another mnemonic for the quadratic formula:
And let’s not forget the Quadratic Formula Rap:
A great piece in the Guardian, “Am I too old to learn a new language?” The answer is no.
‘Despite the difficulties, Black regards learning foreign languages as fun, and treats the endeavour like a puzzle that has to be solved. “I’m doing it partly to keep my brain active,” he says. “When you have some success and can express yourself, it feels like you’re using different parts of your brain that you weren’t using before.”
Indeed, research shows that bilingual children use the same brain regions for both languages if they are learned during childhood, whereas learning a second language later on in life recruits different regions from those involved in using one’s mother tongue. And learning a foreign language, much like learning to play a musical instrument, does indeed appear to be a good way of exercising one’s brain, and keeping it healthy, throughout life.’
Here is an interesting TED talk on language learning and teaching:
