Dubai has successfully tested the first flying taxi

Dubai has successfully tested the first flying taxi     Dubai is looking to stand out as a high-tech hub in its region. A test flight of what is said to be the world’s first drone taxi service was conducted in the United Arab Emirates city on monday. An unmanned craft, developed by German drone maker Volocopter, was successfully tested in a ceremony put on for Dubai Crown Prince Sheikh Hamdan bin Mohammed. The Volocopter vehicle is a two-seat, eighteen-rotor vehicle, which takes off and lands vertically. The vehicle is meant to fly autonomously for up to 30 minutes, making it ideal for short-distance urban travel. The goal of the project is to grow into an Uber-like platform here users can pull out their phones and order a ride at the nearest “voloport.” The vehicle is equipped with a number of fail-safes in the event of something going wrong. Items like extra batteries, rotors, and parachutes ensure passenger safety. Mostrar detalle

Polynomials evaluated at integers by John D. Cook

Polynomials evaluated at integers by  John D.  Cook     Let p(x) = a0 + a1x + a2x2 + … + anxn and suppose at least one of the coefficients ai is irrational for some i ≥ 1. Then a theorem by Weyl says that the fractional parts of p(n) are equidistributed as n varies over the integers. That is, the proportion of values that land in some interval is equal to the length of that interval. Clearly it’s necessary that one of the coefficients be irrational. What may be surprising is that it is sufficient. If the coefficients are all rational with common denominator N, then the sequence would only contain multiples of 1/N. The interval [1/3N, 2/3N], for example, would never get a sample. If a0 were irrational but the rest of the coefficients were rational, we’d have the same situation, simply shifted by a0. This is a theorem about what happens in the limit, but we can look at what happens for some large but finite set of terms. And we can use a χ2 test to see how evenly our sequence is compared to what one would expect from a random sequence. Mostrar detalle

¿Qué es la malaria?

¿Qué es la malaria?     La Malaria es una enfermedad parasitaria que involucra fiebres altas, escalofríos, síntomas seudogripales y anemia. Causas La malaria o paludismo es causada por un parásito que se transmite a los humanos a través de la picadura de mosquitos anofeles infectados. Después de la infección, los parásitos (llamados esporozoítos) viajan a través del torrente sanguíneo hasta el hígado, donde maduran y producen otra forma, llamada merozoítos. Los parásitos ingresan en el torrente sanguíneo e infectan a los glóbulos rojos. Los parásitos se multiplican dentro de los glóbulos rojos, los cuales se rompen al cabo de 48 a 72 horas, infectando más glóbulos rojos. Los primeros síntomas se presentan por lo general de 10 días a 4 semanas después de la infección, aunque pueden aparecer incluso a los 8 días o hasta 1 año después de esta. Los síntomas ocurren en ciclos de 48 a 72 horas. La mayoría de los síntomas son causados por: La liberación de merozoítos en el torrente sanguíneo Anemia resultante de la destrucción de glóbulos rojos Grandes cantidades de hemoglobina libre liberada en la circulación luego de la ruptura de los glóbulos rojos Mostrar detalle

Entomología

Conociendo la rica biodiversidad de Venezuela. Memphis basilia "Mariposa hoja" @MIZAUCV

Conociendo la rica biodiversidad de Venezuela. Memphis basilia "Mariposa hoja" @MIZAUCV     DIAGNOSIS.- Size: 76-80mm. A large species showing a pronounced sexual dimorphism. Although very close in facies to related species, it can be distinguished by a series of comparative characters: Memphis alberta (Druce) - - forewing apex less falcate; Memphis iphis (Latreille) — different underside pattern of the wings; Memphis moeris (Felder) — forewing apex slightly less falcate, wings slightly thinner, ground color of the upperside basal area in males darker blue (same as in M. alberta) without the greenish sheen, and in females, deeper sky blue, subapical blue patches better marked, basal blue (in male) not reaching the tornus incurvation. Additionally, male genital structure allows the recognition of this species. Mostrar detalle

Radio

Reginald Fessenden, the Canadian inventor of radio telephony by IEEE

Reginald Fessenden, the Canadian inventor of radio telephony by IEEE     Reginald Fessenden -- Pioneer of wireless radio and telephony (The Radioscientist) IN THE BEGINNING WAS THE WORD If Canadian radio archives do not contain as much material as they should, there is one historical event well documented - the achievement of Guglielmo Marconi, an Italian who made radio history by transmitting the letter "s" in Morse code from Cornwall, England to a receiving station on Signal Hill overlooking St. John's Harbour in Newfoundland on December 12, 1901. But an equally historic event, the achievement of a brilliant Canadian inventor, Reginald Aubrey Fessenden, is generally ignored and largely unknown. On December 24, 1906, at 9 P.M. eastern standard time, Reginald Fessenden transmitted human voices from Brant Rock near Boston, Massachusetts to several ships at sea owned by the United Fruit Company. The host of the broadcast was Fessenden. After giving a resume of the program Fessenden played a recording of Handel's "Largo" on an Ediphone thus establishing two records - the first recording of the first broadcast. Fessenden then dazzled his listeners with his talent as a violinist playing appropriately for the Christmas season, "Oh Holy Night" and actually singing the last verse as he played. Mrs. Helen Fessenden and Fessenden's secretary Miss Bent, had promised to read seasonal passages from the Bible including, "Glory to God in the highest -and on earth peace to men of good will," but when the time came to perform they stood speechless, paralyzed with mike fright. Fessenden took over for them and concluded the broadcast by extending Christmas greetings to his listeners - as well as asking them to write and report to him on the broadcast wherever they were. The mail response confirmed that Fessenden had successfully invented radio as we know it. Technically, he had invented radio telephony or what radio listeners would call "real" radio as opposed to Marconi's Morse code broadcasting. Fessenden could truly lay claim to be the inventor of radio and he fully expected the world to beat a path to his door. Instead, he never received his due recognition, lost control of his patents and the ensuing revenue which made other inventors and companies immensely wealthy. Even today the Encyclopedia Canadiana does not give him a separate listing. Mention of him is only included under the listing for his mother Clementina who established Empire Day in Canada. Reginald is mentioned as one of her four sons, "inventor of the wireless telephone, the radio compass and the visible bullet for machine guns, he also invented the first television set in North America in 1919."

OWL

10 awesome owl photos for International Owl Awareness Day

10 awesome owl photos for International Owl Awareness Day     More often seen than heard, owls are amazing birds. With fluffy feathers, large eyes and dramatic facial expressions, these birds of prey have long been fan favorites. There are 150 species of owls worldwide and 19 that call North America home, providing plenty of opportunities to spot these birds on public lands or in your backyard. While they may look adorable, owls are fierce hunters. These well-adapted predators are silent hunters with excellent eyesight and hearing, allowing them to soar through the night sky in search of prey. Some scientists estimate that a single owl can eat 2,000 rodents a year. These majestic birds are often associated with wisdom in pop culture, and we figured the wisest way to celebrate International Owl Awareness Day was by sharing awesome facts about some of our nation’s owls. Plus, the photos are a real hoot! Mostrar detalle
