meh the higher ranked schools have so many students in a classroom it's not like you can challenge the teacher.

Ideally Khan will turn into a pay-for solution if you want. You can watch the vids for free, but you can get access to a "TA" for a fee. Using special interface or software that Khan designs, watch video and place bookmarks + comments at parts you have questions on or want to challenge, then get customized responses by the TA.

I wonder if that would influence the videos in the wrong direction...make them intentionally confusing or wrong so that you want to challenge them...hm...

that's why copyright was set to expire after 15 years (or 10 or 20...it was much shorter than the 75-95 years we have now [thanks Disney]), under the founding fathers' original plans. This meant
1. you must keep creating content in order to keep making money
2. your old content enters "culture" quickly and does not remained locked away forever like Walt Disney's greatest creations or Star Wars to be sold again and again for $$$profit$$$ to every generation.

air is a horrible dielectric, not to mention the "cancer" you'd probably get from driving over the equivalent of 1000 cellphones all transmitting at the same time.

once again, you shouldn't have been given a driving permit if you didn't understand that you might need to "pump" the brakes in an emergency situation such as when the brakes lock up in the rain, or if the engine cuts out.

shouldn't we mandate a safety mechanism to save the mechanics? Perhaps a display and camera that shows how close the mechanic's hand is to detonating the airbag? One display for each camera, should only add a few hundred bucks...

If you can't think fast enough under pressure to solve this "puzzle" (one which you should have been prepared for before even being given your drivers permit), then you shouldn't be driving.

if you can't think fast enough to solve the problem you just created for yourself in turning the key to the "off" position from the "on" position, then you shouldn't be driving and never should have been given a license.

starting this year we have to pay the liability + 10%

and it keeps them afraid of tax reform.

Everybody is afraid they're going to lose special interest pork-barrel xyz so we end up with a >30,000 page tax code, which the politicians love because nobody can make sense of whatever extra special constituent tax refund pork they want to cram in to next year's code.

Meanwhile big companies get bigger, and the middle class with its smaller companies (that can't afford lobbyists) eat the brunt of the tax burden, away they go and the business goes to the big companies.

hm throwing from a building, that's a great idea.

due to its erratic flight, it let you use the full gymnasium, much more exciting than anything that flew in a straight line....

just because it sounds like a bird doesn't mean it....

to show how useless TSA is.

pshaw, I've seen movies, kid, movies with explosive devices. They always look electronic and have exposed wires. Usually you cut the blue one.

AND TEH PLANES. I am GROUNDING THE PLANES until further notices. Because I am their parent too I can ground them :D
