1905 Darracq 200HP land speed record car seriously sideways
I like the little oscillating thingy-ma-bob that's visible in the head on shot. It makes it look like the driver is pedaling the car like a bicycle.
edit: Oh, it's the license plate. Serves me right for not watching in full screen.
Why Bikes Stay Up - MinutePhysics
I bet you're remembering the clip of Richard Feynman explaining that function here on the sift?
http://videosift.com/video/How-a-Train-Stays-on-a-Track-not-as-simple-as-you-thought
I remember being fascinated by that. I don't think it has anything to do with this function in bicycles, but on the other hand I had no idea that was how trains stayed centered over the tracks either...
I wonder if it has anything to do with why train wheels stay on the rails due to being tapered, and the flange is only there for emergencies. They're self-centering.
Like, when the bike wheel turns, it becomes effectively a larger system that wants to return to being smaller.
It's Soccer ... On Bicycles!
Also more interesting than bicycle polo, as it really uses the bike. It might be more interesting on a larger field, however.

Would've been funnier if the guy was riding a bicycle.
This is How Good Cops Act: Heroic Officer Refuses to Shoot
Bicycle, the last sentences showed me that you have a level head and stopped me from my knee-jerk reaction... The case here was from the start a very possible deadly force.
Double murder suspect...the guy had nothing to lose, already by judgment of safety, because he murdered two people and lets be honest, if he killed the cop he now had another gun. It is not the officer I worry about (though it would be sad if he lost his life) but the innocent guy driving by who gets shot for his car.
Second, the guy here obviously had a method to murder people. Whether he killed those two with a knife or gun would be irrelevant. I can kill you with a knife within 21 feet before you have time to draw your weapon, and that is a fact.
Third, 8% of officers die by their own weapon. That is not a small number. I would play the lotto with those odds...just saying. Once in hand to hand you better be able to win regardless of their skill...
You shoot to kill because of what might happen, not what has happened. Drawing the gun was 100% right. That four seconds where you are scrambling is three shots from the bad guy--at least I can get off three.
Breaking News: Cop does NOT shoot suspect.
While I think its a good thing that he didnt shoot, I'd go even further and complain that he did DRAW a gun. That might have been warranted in this situation, but it seems to be standard practice to draw the gun (accompanied by loud, aggressive shouting) as soon as possible. It seems to me that this tactic is inherently unhelpful on several levels, firstly it makes it much easier to end the situation by trigger-pulling, secondly, but perhaps more importantly, it heightens the tensions and the stakes. Someone who has a gun drawn on them will intutively react with a form of panic. This combination is a recipe for a lethal ending.
Naturally, I understand the fact that the police has a dangerous job, and sometimes the threat of lethal force is warranted, but the bar should be high. Very, very high.
9 month old Baby goes bodyboarding with Dad
They know to float and hold their breath due to a natural response, which you can emulate by blowing in their faces, to which they have the same reaction. They also flap their arms and legs in a swim-like motion so that a layman might think they know how to swim.
Actually they are not strong enough nor understanding of the concept to hold their head above water to breathe. Your advice is misleading and it could be dangerous if taken in the wrong way. Babies cannot swim and are at significantly higher risk of drowning than older/stronger (even non-swimmer) children, and they're naturally shaped and weighted to float face down.
Suggesting that we have an unnatural, unnecessary fear of babies drowning in the west sounds like jenny mccarthy new-age nonsense.. we have a rational fear of babies drowning because they are at risk of drowning for aforesaid reasons, which is aside from whether this video is safe for a baby or not... some people take their babies on bicycles and in cars in at least equally dangerous environments.
No offence intended, but drowning is a serious risk for small children, and what you say is a hazardous myth... babies will survive being submerged for a short period of time, and will not try to breathe when submerged. They cannot swim and will drown if not retrieved quickly.
Babies know how to swim from the womb. Most westerners are too terrified (of everything, generally) to allow babies to try though. So they loose the skill and learn the fear.

New regulation in effect in Baden-Württemberg: any new appartment building has to include two weatherproof bicycle parking spaces for every appartment.
I don't own a car anymore, been taking my bike everywhere for more than a decade, so... yay. No more cluttering the hallways with dirty bikes. Then again, I live on the other side of the country.
Fyi: Greens run Baden-Württemberg.

Almost Darwinned herself on a bicycle...
Oh, I agree that what the woman on the bicycle did was profoundly stupid and she should have waited for the signal or at least recognized the dangerous situation she was in re: oncoming traffic. She put everyone else in a dangerous and easily avoidable situation. At the same time though, were I driving the oncoming car, I would be slowing down and covering my brakes at the crosswalks, anticipating that a pedestrian might dash out from between the cars (happens a lot, though they usually stop short right after freaking me the hell out). In many places, hitting a pedestrian on a crosswalk is your fault regardless of the signals.
I'll certainly also grant you that a collision in the situation was probably unavoidable given how fast bike lady was going, but I also can't approve of the oncoming driver. Of course, speed is hard to gauge in the video, but they seemed to be just driving along at a constant high-ish speed assuming having the right of way means you don't have to watch out for idiots doing foolish thing.
Also, I see it as a reasonable (though stretched in this instance) rule of thumb that in a dense urban environment, if you have to swerve to avoid a pedestrian rather than just braking, you weren't driving carefully enough.
I disagree. The oncoming driver reacts quickly and swerves to the side. He/she's the reason the cyclist walked away from it instead of being hospitalised.
Also, she's cycling in an urban area (i.e. interacting with cars) without a helmet. She's an idiot.

cops pepper spray crowd
More context needed to make a decision on this. What happened before this was shot. Something caused the cops to circle the bicycles and take a defensive stance.

There's a lot of fail all around. Even though the woman operating her bicycle foolishly is the root of everything, I also see a failure of signage and a failure of adequate caution on the part of the oncoming driver.
