How does Snickometer Technology work?

The cricket Snickometer (known as 'snicko' for short) was invented by English Computer Scientist, Allan Plaskett, in the mid-1990s. Snickometer technology was first used in 1999 by Channel 4 in the UK, before being used in India and Australia.

The snickometer is composed of a very sensitive microphone located in one of the stumps, connected to an oscilloscope that measures sound waves. When the ball nicks the bat, the oscilliscope trace will pick up the sounds. At the same time, a high speed camera records the ball passing the bat. The oscilliscope trace is then shown alongside slow motion video of the ball passing the bat, and by the shape of the sound wave you can determine whether of not the noise picked up by the microphone coincides with the ball passing the bat, and whether the sound seems to come from the bat hitting the ball or from some other object.

This technology is used in televised cricket matches to graphically show the video of the ball passing the bat at the same time the audio of any sounds at the time. It is only used to give the television audience more information and to show if the ball did or did not actually hit the bat. The umpires does not get the benefit of seeing 'snicko'.

As the ball passes the bat, there can be other noises that can be confused with the ball on bat noises. The bat often hits the pads on the way through, making a sound at the same time the ball passes the bat. The sound/sound wave is purpotedly different for bat-pad and bat-ball, but this is not always clear. The shape of the recorded soundwave is the key - a short sharp sound is associated with bat on ball. The bat hitting the pads or the ground produces a flatter sound wave.

What is the smallest possible Distance in The Universe?

In physics, the Planck length, denoted ℓP, is a unit of length that is the distance light travels in one unit of Planck time. It is also the reduced Compton wavelength of a particle with Planck mass. It is equal to 5.72938×10⁻³⁵ m (Lorentz–Heaviside version) or 1.61623×10⁻³⁵ m (Gaussian version). It is a base unit in the system of Planck units, developed by physicist Max Planck. The Planck length can be defined from three fundamental physical constants: the speed of light in a vacuum, the Planck constant, and the gravitational constant. It is the smallest distance about which current, experimentally corroborated, models of physics can make meaningful statements. At such small distances, the conventional laws of macro-physics no longer apply, and even relativistic physics requires special treatment. The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10 -35 m across. It is impossible to determine the difference between two locations less than one ...

How do Ants sense Food?

S ugar has a slight odor, particularly granulated beet sugar. While all species of ants can differentiate between a wide variety of odors, the smelling range differs from a few centimeters to meters. Desert ants can smell sugar from up to 3 meters. the food sources that ants cannot smell from a distance they 'smell' it (contact chemoreception) by touching it. So in a way, all the food they detect, they detect it by smelling. So yes, ants smell (although contact chemoreception is more like taste) the sugar. The ant colonies send scout ants to search for food in various directions, often up to a range of 100 to 200 meters.(Depends on the territorial boundary and time of the year). The scout marches steadily in less circuitous paths initially if it has memories of previous feeder locations. (Ants use visual landmarks, and a stereo-smell system to create an odor map and navigate) Periodically it will halt and look for olfactory cues. It will then take into a more circuitous rando...

WATCH INSTAGRAM STORIES ANONYMOUSLY!!!?

If you want to see anyone's Instagram story without letting them know, If you've ever wanted to be a fly on the wall at an Instagram Story, then this blog post is for you. In this post, I'll tell you all about the best websites that will let you watch anyone's stories anonymously. In addition to that, you will not need to login into that website. Ahead of time, though, there are a few things that everyone should know before trying to spy on someone else's Instagram Stories. You need to have a bit of patience in order to make this work, given that there's always a chance that the one you're spying on could beat you to it. Most importantly, you can't expect this to work for every account that you try it on. There's also no way of knowing how much of the stories you'll actually be able to see and how long the access will last for. However, you cannot be able to see the stories of those who have a private account. below are the links to some websit...
