The first cell phone call was made by Martin Cooper (born December 26, 1928), a researcher at Motorola, on April 3, 1973. Cooper was working on developing the first handheld mobile phone, which he called the DynaTAC. The phone was large and bulky, weighing about 2.5 pounds, and it had a battery life of only …

Agricultural practices are greatly affected by climate conditions, as changes in temperature and precipitation patterns have led to shifts in crop growth and yields. Warmer temperatures are responsible for increased evaporation rates, leading to dry soils and reduced crop growth.
An essential step towards a carbon-neutral future could be reached through dispersed power grids, featuring networks of local-scale renewable energy and battery storage plants. To prevent these power grids from damaging themselves and their surroundings when electrical faults arise, they must be integrated with “circuit breakers”, which temporarily interrupt the current flowing through them. However, …

Electric vehicles are having a moment in the sun thanks to significant pushes to invest in the performance and energy efficiency of EVs. While electrifying our lifestyles isn’t perfectly clean energy, it significantly reduces our carbon footprint by lessening our nonrenewable energy consumption. This leads many to ask – can we electrify our homes while …

On September 9, 1947, a team of computer scientists and engineers operating Harward University’s Mark II electromechanical computer started getting an error. They traced the error and found a moth trapped in a relay. The moth was carefully removed and taped to the logbook with a note saying “first actual case of bug being found”. …

On August 12, 1981, the Personal Computer, (model 5150, commonly known as the IBM PC) was released. This machine (and its descendants) started the PC revolution. It was a very small machine that could not only process information faster than those millions-of-dollars huge computers of the 1960s but also hook up to the home TV …

On August 9, 1991, two STS-43 astronauts aboard the Space Shuttle Atlantis, Shannon W. Lucid and James C. Adamson sent the first e-mail from space. The astronauts used an Apple Macintosh portable computer and AppleLink, a popular service for Mac and Apple IIGS users before the commercialization of the Internet, offered from 1986 to 1994. …

On July 28, 1981, IBM (International Business Machines Corporation) revealed its first desktop computer, System/23 Datamaster, a demonstration of IBM’s efforts to shrink the size and cost of computing.
On July 26, 1963, Syncom 2 (for Synchronous Communication Satellite) was launched on top of a Delta B #20 launch vehicle from Cape Canaveral.
Much of the technology common today that we take for granted originate from the moon landing. Here are 10 moon-landing innovations that changed life on Earth.
