Historic Tech Events
On June 20, 1950, the National Bureau of Standards (NBS) in the United States dedicated the Standards Eastern Automatic Computer (SEAC) machine. The SEAC was a revolutionary invention for its time, being the first operational stored-program electronic computer in the country. The SEAC machine was developed under the leadership of computer pioneer Samuel N. Alexander and his team at NBS. It was designed to perform scientific and engineering calculations, as well as to aid in research and development in various fields. The SEAC had a memory capacity of 512 31-bit words and could perform up to 1,000 additions or subtractions per second. Its storage system was made of Williams-Kilburn tubes, which were among the earliest forms of random access memory.
The Wikimedia Foundation Inc. was founded in 2003 in St. Petersburg, Florida. It is a non-profit organization that supports and operates a number of collaborative and open-source projects, including Wikipedia, Wikimedia Commons, Wikidata, and others. The mission of the Wikimedia Foundation is to empower and engage people around the world to collect and develop educational content under a free license or in the public domain, and to disseminate it effectively and globally.
In 1990, David H. Levy discovered an asteroid which he named Eureka. The asteroid, also known as "5261 Eureka," closely trails Mars at just 0.3 astronomical units away. It is categorized as an Amor asteroid, which means it has a perihelion distance (closest point to the sun) that is greater than that of Earth's orbit. Eureka has an estimated diameter of around 2.5 kilometers and is believed to be a relatively young asteroid, with an age of around 1 billion years. Its orbit is irregular, and it takes about 1.2 Earth years to complete one orbit around the sun. Eureka's discovery has contributed to our understanding of the composition and behavior of asteroids in our solar system.
In 2013, the Chinese astronaut Wang Yaping gave a lecture from space to students back on Earth. The lecture was part of a mission called Shenzhou-10, which was China's fifth manned spaceflight. During the lecture, Wang Yaping demonstrated physics experiments in microgravity, explaining scientific principles to the students through a live video feed. The lecture was broadcasted on television and online, making it accessible to millions of people in China and around the world. This was a significant moment in China's space program, as it demonstrated the country's growing capabilities in space exploration and its commitment to promoting science education.
Samuel Morse was granted a patent for his invention of the telegraph system in 1840. This system revolutionized communication by allowing messages to be transmitted over long distances using electrical signals. Morse's invention used a code consisting of dots and dashes, known as Morse Code, to represent letters and numbers. The telegraph system was widely adopted and played a crucial role in the development of the modern telecommunications industry. Morse's invention paved the way for the development of the telephone, radio, and eventually, the internet.
