INTERESTING FACT OF THE DAY

[Mr Speirs]

Yeah!!! Thats a wrong fact.

[missyburd]

for years tea makers where forced to put bromide in there mix to all the armed forces to subdue sexual desire it only stopped in the early 90's
eeep!

And probably only because the bromide budget got cut.

:pWhen a female horse and a male donkey mate, the offspring is called a mule, but when a male horse and a female donkey mate, the offspring is called a hinny. When a male zebra and a female donkey mate the offspring is called a zedonk or zebrass. All of these resulting offspring are sterile (can't have babies).:p

[vixis]

Yeah!!! Thats a wrong fact.

Isnt there a record of a kangaroo actually coming alongside a motorbike and, using the tail as balance, kicking them off the bike? Or is this an urban myth?

[gettin2dizzy]

And probably only because the bromide budget got cut.
That, and the fact it didn't work! One of my favourite quotes:

"I don't think the bromide had any lasting effect, the only way to stop a British soldier feeling randy is to load bromide into a 300 lb shell and fire it at him from the waist down."
Spike Milligan

[yorkie_chris]

To quote Spike Milligan "the only way to stop a British soldier feeling randy is to load bromide into a 300lb shell and fire it at him from the waist down"

A small tenebrionid beetle living in the Namib desert can secrete wax in response to increased temperatures and humidity which spreads out over its body to create a film for reducing water loss. This idea was adapted by researchers in 2005 and led to the creation of "nano-wicking systems" which attract water droplets and by reducing the contact angles of the droplets with the surface a thin film across it is formed. And thus "anti-fogging" agents are born :-D

[vixis]

That is the best justification for drinking yet! :)

There are over 1000 chemicals in a cup of coffe, and only 22 have been tested.
Seventeen of those 22 chemicals contain cancer causing compounds.

Interesting....if true. Grammatically tho it would have to be "To Assure Prompt Service" or even " To Ensure Prompt Service" ...unless of course its an americansim, lol.

[wyrdness]

The word Tips (As in to tip a waiter) is actually an Acronym and stands for 'To Insure Prompt Service' and used to be given prior to service to insure that you got priority over other customers when getting served.

No, this is entirely incorrect. That's an example of a 'backronym', where an acronym is later attributed to a word. And, as Spidey mentions, 'Insure' doesn't mean 'Ensure'.

If I remember correctly some of the praying mantises will do that. Viscous little buggers too as I saw on in Cofu and it was in the middle of the path hissing at everyone. Even though it was tiny people where giving it a wide birth. lol.

The Sooty Tern is capable of staying in the air for 4 years without landing. They must land to breed however. The European Swift spends the first 3 years of its life on the wing.

Anyhoo... i'd love to know something. How the hell can they know that a bird stayed in the air for 4 YEARS unless they'd already tagged it of course but i idint think they went out and tagged birds out there. Anynone know how they proved this 4 yr flight-time thing?

It has been reckoned that there are 100,000 miles of blood vessels in the human body.

This would mean a velocity of blood of an average 8050000m/s. .338 rifle round is about 850m/s...

Still makes no difference. The entire frame of reference is rotating - the earth, the air, etc - and its not accelerating, therefore it can be considered stationary. It will not affect the bullet whatsoever.

That is not what affects the bullet.
The effect comes from the difference in rotational speed where the objects inertia goes someway to offset the force of gravity on it.

2 objects - the earth and the bullet. Difference of rotational speed is the same regardless of which direction you shoot.

[yorkie_chris]

2 objects - the earth and the bullet. Difference of rotational speed is the same regardless of which direction you shoot.

So you shoot east; rotation is effectively faster.

F = m v^2 / r .... v gets bigger, F gets bigger, force required to hold same arc is bigger, only force there is weight = mg.

Shoot west; rotation is effectively slower. v gets smaller, acceleration due to gravity is offset less. Trajectory is shorter.


You are correct that dV is same either way, but the sign of the difference does matter even though v term is squared.

I suspect that, even with a super high velocity bullet, the difference would not be measurable.

and monkey its not the colour it the shape of the gun curvy ones shoot better:rolleyes::p:D

As I understood it, a curvy gun would be something like a Blunderbuss (http://blindkat.hegewisch.net/pirates/blunbuss.html), where the pipe the bullet comes out of curveswards. Rubbish idea!

Where as a pointy gun like a barrett (http://www.inetres.com/gp/military/infantry/rifle/M107.html) has a nice pointy end that fires a bullet to where you want it.

Yet again, more evidence why a pointy is best! :smt019

Calibre and bullet shape all affect the ballistic coefficient which you use to work out the elevation based on range, muzzle velocity etc.

ammo temp yup, powder burns quite a lot slower at colder temps. Can be up to a few 100 feet per second difference!

:lol: that doesn't really work as tracers are lighter than normal bullets (I think they put 1 tracer in every 3 rounds), probably only work in the dark and the target will have taken cover by the time you adjust.
