    Not in this case. That's what the extensive testing was all about ;)

    You submit them for publishing as a paper in a scientific journal. You wait for the peer reviews which will test your methodology and ideas and if it's accepted, you get the credit. Expect to be challenged - that's how science works. You build a theory and then do your best to destroy it -...

    Athletics 'Blade runner'

    The blades give the same level of advantage that possessing a pair of lower legs does. It's been tested thoroughly and if it hadn't and met the required standard of no net advantage then they wouldn't be allowed in competition.

    Athletics 'Blade runner'

    You won't jump 4 feet from a standing start - you'll have to build momentum and you'll still be putting more energy in than you get out. In the case of a bladed and able bodied runner both have to overcome inertia and build speed and momentum, both are subject to the same fatigue mechanisms and...

    Athletics 'Blade runner'

    As I've said in a previous post, an athelete using blades to compete at that level will be at the same standard of fitness as an able bodied athelete and at the risk of repeating myself further, a blade still relies on the long muscles of the upper leg to propel the athlete forward as does the...

    ideas/inventions

    I'd be interested to know how you think you'll benefit from any idea that would fundamentally chance the scientific method - it's not patentable anyway and to be accepted you'd have to have it peer reviewed. Come to think of it, I'd be even more interested to know how you think you could...

    Athletics 'Blade runner'

    I'd bet the blades will have to meet some sort of standard - in any event you'll never get more out than you put in and that's a given. The muscles that make the difference for a runner are the big long muscles in the upper leg anyway.

    Athletics 'Blade runner'

    Most of the energy comes from the large muscles in the upper leg and so blade users are still subject to the same fatigue and strain as an able bodied runner - maybe even more so as there will be more muscle action required to preserve balance as well as impel the body forward. The calf muscles...

    Not at all - it's not that difficult to measure the amount of energy returned for a given input.

    Athletics 'Blade runner'

    They've been extensively tested and shown to provide no more advantage to an athlete than legs. The energy stored in the blades as they flex is much the same as that in muscles and tendons.

    Who the f*** do China think they are?

    lol AP: "KATMANDU, Nepal (AP) — Nepal has ordered a new measurement of Mount Everest to determine exactly how high the world's highest mountain is. The Himalayan country has continued to recognize the decades-old measurement of 29,028 feet (8,448 meters) though Western climbers and...

    Who the f*** do China think they are?

    Ahem... "Nepal has ordered a new survey of Mount Everest to end the "confusion" over the exact height of the world's highest mountain, a government spokesman has said. The official overall height of Everest is designated as 8,848m (29,029ft). But China and Nepal have had a long-running...

    Who the f*** do China think they are?

    The poles have nothing to do with height. Summits of mountains in the UK are indicated by OS trig points - cairns are used on both summits and routes as positional markers - they can be important when you're trying to fix a bearing off of a summit or stay on a path in poor visibility...

    Who the f*** do China think they are?

    China thinks it should be measured by rock height. Nepal thinks it should be measured by snow height. The difference is around 4 metres. Tectonics are slowly increasing the height of the mountain anyway as India subducts under Asia and it's being constantly weathered and eroded too.

    Putting up shelf, need advice please.

    1. They should run the full depth of the shelf 2. They should be screwed securely to the studwork at as many points as possible - 2 minimum though. Make sure the screws you use are long enough to go through both batten and plasterboard with enough additional length to go deep into the...

    Putting up shelf, need advice please.

    If you want it to support a heavy load then plasterboard fixings aren't up to the job. You really need to fix your support brackets directly into the studwork or masonry behind if it's dot and dabbed.

    Wear gloves too - if you get it on your hands then it's a bugger to clean off :wink:
