1. ### Standard Model Facts for Kids

kids.kiddle.co/Standard_Model

May 22, 2020 · Bosons are the second type of elementary particle in the standard model. All bosons have an integer spin (1, 2, 3, etc..) so many of them can be in the same place at the same time. There are two types of bosons, gauge bosons and the Higgs boson. Gauge bosons are what make the fundamental forces of nature possible.

2. ### Standard gauge Facts for Kids

The standard gauge (also called the Stephenson gauge after George Stephenson, or Normal gauge) is a popular rail gauge. About 60% of the world's current railway lines use this gauge. The distance between the inside edges of the rails of standard gauge track is 1,435 mm (4 ft 8+ 1 ⁄ 2 in).

3. ### Rail gauge Facts for Kids

kids.kiddle.co/Rail_gauge

Rail gauge is the distance from the inside of one rail on a railroad track to the inside of the other. Most countries use a standard gauge of 1,435 mm (4 ft, 8 1/2 in). Wider gauges are called broad gauge, smaller gauges are called narrow gauge. Broad gauge may be used where the track needs to have heavy things moving on it.

Other standards make things work together. For example rail cars with a standard gauge can run on tracks that follow the same standard. Measurement. The International System of Units is a standard that is agreed on by most countries. In it there is metre (or meter). It measures length.

A rain gauge is an instrument used by meteorologists and hydrologists to measure precipitation (e.g. rain) in a certain amount of time. It usually measures in millimetres.Rain gauge is an meteorological instrument for determining the depth of precipitation (usually in mm) that occurs over a unit area (usually one metre squared) and thus measuring rainfall amount.

en.wikipedia.org/wiki/Model_kit

Although model railways were also built to different gauges, "standard gauge" in 1:1 scale railroads is 4' 8.5". Therefore, a model railway reduces that standard to scale. An HO scale model railway would have track that is 1/87 of 4' 8.5", or about 0.65" from rail to rail.

Therefore, the Standard Model is often referred to as SU(3)×SU(2)×U(1). The Higgs boson is the only boson in the theory which is not a gauge boson; it has a special status in the theory, and has been the subject of some controversy. Gravitons, the bosons believed to mediate the gravitational interaction, are not accounted for in the Standard ...

Unlike the older lines, Shinkansen lines are standard gauge, and use tunnels and viaducts to go through and over obstacles, rather than around them. Construction of the first section of the Tokaido Shinkansen between Tokyo and Osaka started in 1959. The line opened on October 1, 1964, just in time for the Tokyo Olympics.

In 1991, construction started on a standard gauge railway from the steel mills at Ajaokuta to the port of Warri, about 275 km away. By 2006, the standard gauge lines had reached 329 km in length, but the final 27 km Warri section is still incomplete. In 2010, work recommenced to complete that final section to Warri. Road
