February 24 has long and varied historical events. Today, Bragsocial again takes you the branch of knowledge dealing in past events on this day. The events includes the discovery of a pulsar, zircon crystal, Mariner 6, and other interesting events.
1839: Steam Shovel monopolized by William Otis, Philadelphia.
Americans invent on February 24, 1839. William Otis receives a patent, #1089, for the steam shovel for excavating and removing earth. Abstrusely, he named it the Crane-Excavator for Excavating and Removing Earth. The patent was for a system of pulleys, cranes, and utilization of the existing steam engine to lift earth in a bucket to railroad cars. Besides, the capacity of the container at the time was 380 cubic meters per day. His machine was the earliest to employ the principle of a single-bucket excavator swung from the center. Also, it was provided with a powerful thrust for adjusting the radial thickness of the cut.
1857: LA Vineyard Society organized.
The idea for the Los Angeles Vineyard Society started in the city of Anaheim when the first German settlers settled there. Plans for a vineyard society as discussed materialized into a cooperative venture had their first recorded meeting on February 24, 1857. In fact, Los Angeles was the primary center for winemaking in California. The Missions were the teachers and greenskeepers for the laypeople. The Gold Rush created a new wine market, as a result, people making wine in Los Angeles could ship north in large quantities.
1968: Discovery of the first pulsar announced (CP 1919).
In 1967, when Jocelyn Bell (then a graduate student in astronomy) observed a strange ‘bit of stuff’ in the data coming from her radio telescope, she and her advisor Anthony Hewish initially thought they might have discovered a signal from an extraterrestrial civilization. It turned out not to be aliens, but it was still quite exciting: they have discovered the first pulsar. They announced their discovery on February 24, 1968. The announcement caused quite a stir.
1969: Mariner 6 initiated for Mars flyby to study the planet’s atmosphere.
Mariners 6 and 7 were outlined to fly over the equator and southern hemisphere of the planet Mars. Both spacecraft were attitude stabilized in three axes. Jet Propulsion Laboratory invented Mariner 6 on February 24, 1969. One hundred kilometers (62 million miles) later, Mariner 6 encountered Mars on July 31, 1969. The spacecraft studied the Martian atmosphere and profiled its chemical composition. Moreover, Mariner 6 photographed the surface of Mars at a range of 3,459 kilometers. The area is computed 901 kilometers by 692 kilometers and is placed southeast of Meridiani Sinus about 15 degrees below the equator.
1976: Cuba adopts its constitution.
Cuba had several constitutions since winning its independence. The country drafted its first constitution in 1976 and has since been amended. It took effect on February 24, 1976. This constitution re-committed the state to issue its citizens with access to free education and health care. Furthermore, it also gave freedom of speech, the right to assemble. The state was further given the power to monitor the activities of religious institutions and the private ownership of media was prohibited.
1997: Qatar inaugurates the world’s largest liquefied natural gas exporting facility.
On February 24, 1997, Qatar commenced the World’s immense liquefied natural gas (LNG) exporting facility and formally launches the Qatar Liquefied Gas Company. It will have a total output capacity of 6 million tons per year of LNG. The facilities are a part of a new $7.2 billion industrial zone which also includes a seaport with an extent to handle 25-30 million tons of LNG annually.
2014: A 4.4 billion-year-old Crystal invented.
Scientists discovered the oldest fragment of Earth’s crust and it is blue. This 4.4 billion-year-old zircon crystal was only 200 million years old when it took shape in the calamitous chemical environs of Earth’s infancy. The scientists make use of a technique – atom probe tomography that was able to recognize individual atoms of lead in the crystal and determine their mass. Moreover, it computed only about 200 by 400 microns.
