Rolling Different Tires Down A Ski Jump Hill

jubuttib says...

Being a Finn I do watch a certain amount of ski jumping, and no, that ramp at the end isn't there when people jump. It's probably just there to "simulate" the jumping motion of a ski jumper (infact, I think they explain that in the video).

I do think rolling resistance does play a part in all this, just not sure how big a part. The F1 tyre is slightly heavier (longer jump), has a slightly smaller radius (longer jump, according to arvana) than the sports car tyre, and jumps the shortest. What I know of F1 tyres is that they are very very sticky and have very poor rolling resistance (that is "lots of it"). Also of course it's way wider and hence has more drag, but that isn't enough to explain the difference. So yeah, I think we need more testing. I live only a few kilometers from the Puijo K-120 hill (also has two smaller ones) and am going to find out what it would take to get them to let me try this. =)

But what we really need is someone trying this on the mother of all ski jumping hills, the Planica (K-185, record 239+m, Ahonen jumped even longer but couldn't stay up) with a sturdy ramp that can take on the 220kg tyre. Also we need rocket boosters to get the speed up and over 200kmh. =)

christmas according to the bible

>> ^nadabu:
I do not do these things as worship to my God; i do them as fun family traditions that brighten up some of the darkest and coldest weeks of the year. God doesn't want us to worship him as pagans worshipped their gods, but that doesn't mean we can't do those same things for other reasons.


Yeah, it's not like he brought an evergreen from the forest inside his house and decorated it with the symbolic entrails of woodland creatures on the shortest day of the year when the sun begins it journey back to the south again.

I mean that would be like Pagan rituals, and the one true God clearly wouldn't want that.

Cat jump: FAYL

joedirt says...

LOL.. my cat is always doing stuff like this. I leave papers on desks for much entertainment on jumping up.. and then this slow motion O SHI- sliding backwards..

And for L-shaped desks, a little paper near the corner is hilarious. Damn cat always tries to take the shortest route and somehow can't remember what the desk is like and always pulls one of these chin smacks when it steps on the paper.

A short story in stop motion.

Chomsky on socialized medicine

10898 says...

Choggie, I have done a fair deal of research into the topic of Single Payer Health care systems and I have to object to your glib and one sided presentation of the topic.

First suggesting that the distribution of health care resources is an 'ancillary issue' that we 'hem and haw over' is really selling the issue short. People live and die based on the stance we take. While you could validly argue that there are more important issues out there, that does not mean that this individual issue is unimportant.

Secondly your description of America's top notch health care only truly applies to the clinics that are available to those with enough money. Meanwhile many lower/lower middle class Americans choose not to completely mortgage their future and wind up far more ill or dead because of this decision. While America does have the best health care in the world, its limited availability has resulted in America having one of the shortest life expectancies and highest infant mortality rates in the western world.

Third, the flaws that are admittedly present in more socialized health care systems are not sufficient to completely disregard it as a possibility. People are often forced to wait and taxes would be noticeably higher. However, all Americans would be able to go to see medical professionals, even when they do not require emergency medical care.

Finally, a more socialized health care system could be beneficial to our economy. Though taxes would rise, people would not be paying the same ungodly insurance rates or hospital bills. People would feel far more financial freedom as they can now spend more of their hard earned money on themselves, without having to worry about one injury putting them in the poor house.

While I admit that their are valid objections to socialized health care/ health insurance, the hostile rejection it often receives is completely unneeded. We can discuss the topic without resorting to narrow mindedness, generalizations or petty name calling.

This brush is very similar to the brush that I use, and I think it's the best one out there. It may seem pricey, but it is totally worth it. It won't fall apart, and it's a great design and really gets the most fur out in the shortest time. I've only had mine for a little less than a year (got it at a County Fair last summer for only 25 bucks), and I've seen these brushes go for 50-70 dollars in pet supply stores. Before that, I would use a flea comb and a slicker brush which worked decently, but after getting this brush, I never went back.

Thanks for that... I've tried the mitts and a "Zoom Groom"- she hates 'em. I've got a couple different brushes too- do you have a specific reccomendation for brushes to try?

In reply to this comment by Issykitty:
Fur real? (Sorry.)

Is your cat an adult, or is she still young? I'm guessing she isn't accustomed to being brushed regularly. Even though my Issy is short-haired, she is VERY used to being brushed. In fact, she quite enjoys it! She likes follow me into the bathroom and jump up on the (closed) carpeted toilet and is basically telling me that she is ready for a brushing. I've brushed her since she was a itty bitty kitty, and it's supposed to be a great activity to help you bond with your cat. All I can say is, make sure you have a really good brush/ de-shedder. I have one that looks like a metal rake, and it gets a LOT of loose hairs out very efficiently. Try getting a firm hold of her scruff so that you may avoid getting bitten or scratched, and only brush her in very very short sessions. Maybe you can slowly get her accustomed to it, and maybe she will even learn to like it. Hope that this is of some help, and good luck!

edit: I just thought of something else. There are also grooming mitts available in some pet supply stores, and these might make it easier to get her accustomed to grooming before moving on to the brushings.

19 reasons you shouldn’t live your life based on the Bible (Religion Talk Post)

Doc_M says...

If you cede that God is all-powerful and not bound by time itself, what makes you think He is incapable of having an intimate father-child relationship with every single being in existence? People imagine a person-like figure sitting in a chair somewhere and watching bits and pieces unfold. Why can He not see every single event everywhere and interact as He chooses. He is not limited to the human one-focus-at-a-time cage. Why do I think He cares? I believe He said so, but further, if you had a million children and had the means to have a full-time, meaningful relationship with each and every one of them, wouldn't you, and wouldn't you love it? A billion? A trillion? If you created beings with eternal souls, one-by-one, gave them the capability to live and love and to choose to love or reject you, would you not wish to feel their love and return it as a parent? Wouldn't you want to give them guidance as well?

Why is it arrogant to embrace a God and enjoy a relationship with Him knowing it costs him only a portion of His thought that doesn't compare to the infinity He is capable of? A bible-believer will tell you that God delights in His creation and enjoys the love He can give and receive in return. If there are millions of other worlds out there and billions of inhabitants on each, can He not enjoy that love with all of them as well? Would that not just add to His joy and to His glory?

and Cheesmo, the shortest way to answer your question could be to see this: If God is all-powerful and perfect, then His every move and choice is Right the first time, every time. God does not change. He does however have a character. He IS a certain way and those that sin and reject His being and His ways cannot be with Him. In fact, they are choosing to reject Him! Hence upon his rebellion and subsequent failure, Lucifer and his followers could no longer remain with Him.

The "final sacrifice" wasn't a PR move, it was to fulfill the necessity of justice and law. God (as the Son) took the fall Himself to fulfill the law. If He broke His own law, how could He be called just? He'd just be like us. In many polytheistic ancient religions, gods were very human and flawed. They might consider just scrapping a plan and folding their hand for the convenience of it or to avoid something unpleasant. The Christian God is not this way and maintained His character and law despite the price it cost Him.

Why would He care? Why not?!
