In the past, insurance company can track customers driving to save up the bill at the price of giving up privacy.
Nowadays, researchers can use the starting point along with the tracking data to estimate where that driver traveled.

Time2: 1'33''
In Galton’s basic idea,reaction time was one proxy for human intelligence. However, in Psychologist Michael Woodley's findings, they called into question our cherished belief that our fast-paced lives are a sign of our productivity, as well as our mental fitness.
Time3: 2'39''
In the old theory, gene determines our intelligence although environment factors can boost specific skills.
However, critics aren’t as quick to agree on our apparent downward mental trajectory. Some researchers now think that other measures of reaction times are more telling. In another word, the perception of speed can be deceptive to show the intelligence.
Time4: 1'38''
Chautauqua is the sort of bucolic place where folks like to go for slow-lane vacations because of its leafy 750-acre lakeside campus, where founders pursue a celebration of lifelong learning in a marketplace of ideas.
Time5: 1'02''
From the author's own experience, he found that the minimalist footwear allows the nascent walkers the most sensory feedback from their sweet little feet as they move across the earth.

Two parenting myths that with a little dash of science:
1\sugar makes kids hyper---actually, sugar doesn’t change kids’ behavior.
2\Listening to Mozart makes babies smarter---play music to your child because she loves it and you love it, not because you’re looking to grub a few extra IQ points.

TOP 10 cosmological discoveries:
10. Cosmic microwaves are black body radiation---some non-Big Bang cause was responsible
9. Comic microwave background anisotropies----The small seeds of matter that eventually grew into galaxies would have left an imprint in the temperature of the radiation, causing slight temperature differences between different points on the sky.
8. Space is flat--- the geometry of space was very close to perfectly Euclidean — in technical terms, “flat.”
7. Quasars----bright objects literally on the outskirts of the visible portion of the universe
6. Dark matter----not only was most of the matter in the universe invisible, it was also of some type totally unlike the ordinary matter, composed primarily of protons and neutrons, found on Earth.
5. Dark energy----Accelerated expansion implies that something in space — now called dark energy —is pushing the cosmos apart.
4. Primordial gravity waves----a sign as you can get that inflation instantly after the Big Bang set the stage for the future evolution of the cosmos.
3. Cosmic microwave background radiation----That static was the echo of the birth of the universe, literally the smoke from the Big Bang gun, in the form of microwaves.
2. Island universes----a star in the Andromeda nebula that varied in brightness on a regular schedule.
1. Universe is expanding---- Displacing this one from Number One on the list would require something really radical — like maybe the multiverse |
