If it's about guns, gun rights, gun grabbers or any other related subject, sooner or later it's going to be here. Whether it's sniper rifles, shotguns, WWII arms, ammunition or anything else, we're out there scrounging up anything and everything that we can find. Yes, this is something of an ambitious (some would say impossible) project but we're not quitting until we have it all in one place. Have a look around and see some of what our contributors have put together so far.

OOPS!

Well, this is embarrassing.

We don't seem to have an article of the day for this date. Maybe you could help us out and make or suggest one.
(It's fun! trust us.)

Food for thought
The poorest man may in his cottage bid defiance to all the forces of the Crown. It may be frail — its roof may shake — the wind may blow through it — the storm may enter — the rain may enter — but the King of England cannot enter! — all his force dares not cross the threshold of the ruined tenement!
- William Pitt, 1763

  • Biathlon has its roots as a training exercise in the Norwegian Army, and became an official Olympic event at the 1960 Games. Women’s biathlon was included in 1992. In the past 20 years, it has grown to become one of Europe’s most popular Nordic sports.

Article Of The Moment
A Shadowgraph image of a supersonic bullet. The Bow Shockwave is clearly visible as the V-shaped line at the front-most tip of the bullet (far right).
A bullet bow shockwave is a physical and audible wave created in the air when a bullet travels at supersonic speeds; meaning faster than the speed of sound.

The bullet bow shockwave is the result of air being greatly compressed at the front-most tip of the bullet as it slices through the air. As the bullet moves forward a broadening wave of compressed air trails out diagonally from the bullet tip. The sides of the bullet create a conical waveform. This conical waveform may be audible to a witness as a whip-crack sound.

A bullet bow shockwave will be heard by any witness as long as the bullet speed is faster than the speed of sound, whether the bullet was fired from a weapon giving off an openly audible muzzle blast, or a mechanically-suppress-fired muzzle (silenced weapon) blast. If a bullet is fired from a silenced weapon, a witness can mistake the bullet bow audible shockwave whip-crack for the weapon muzzle blast audible wave, which is a separate audible event. It might be noted here that if one is involved in such an event, that the sound you hear from a silenced weapon will not be from the point of origin. Most humans will perceive the sound as being omnidirectional or as emanating from the bullet as it passes by.

In History

  • This phenomenon may be of primary importance in the "grassy knoll" theory of the Kennedy Assassination.

In fiction

  • This effect was visualized in several bullet time scenes in "The Matrix" Trilogy.
