Monnit’s wireless sensor platform and online monitoring software provide a very affordable, simple-to-setup, feature rich solution that helps meet the growing demand of legislative and public concerns regarding the monitoring of gas leaks and emissions. The mems based wireless carbon monoxide sensor allows you to monitor the level of carbon monoxide (CO) gas in the surrounding air. Monnit wireless CO sensors have a small footprint and low cost but boast industry leading, premium performance specifications and are the longest lifetime sensors in the industry and the only CO sensor on the market powered by a coin cell battery (battery lasts over a year at 1 hour heartbeat).

Attack on the pentagon results in discovery of new mathematical tile

In the world of bathroom tiling – I bet they’re interested too. If you can cover a flat surface using only identical copies of the same shape leaving neither gaps nor overlaps, then that shape is said to tile the plane. Every triangle can tile the plane. Every four-sided shape can also tile the plane. Things get interesting with pentagons. The hunt to find and classify the pentagons that can tile the plane has been a century-long mathematical quest, begun by the German mathematician Karl Reinhardt, who in 1918 discovered five types of pentagon that do tile the plane.

(To clarify, he did not find five single pentagons. Most people assumed Reinhardt had the complete list until half a century later in 1968 when R.

System of Transmission of Electrical Energy

Application filed September 2, 1897. Serial No. 650,343. (No model.) To all whom it may concern: Be it known that I, NIKOLA TESLA, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful improvements in Systems of Transmission of Electrical Energy, of which the following is a specification, reference being had to the drawing accompanying and forming a part of the same. It has been well known heretofore that by rarefying the air inclosed in a vessel its insulating properties are impaired to such an extent that it becomes what may be considered as a true conductor, although one of admittedly very high resistance. Referring to the drawing, A is a coil, generally of many turns and of a very large diameter, wound in spiral form either about a magnetic core or not, as may be found necessary.
