| Not only did the 1970's focus on art and its political history but also its scientific history. Many scientific inventions were created in this era like the floppy disc, micro processor and VCR. Explorations are also made in this era like Apollo 17 and in genetic engineering, the first test tube baby. These inventions and explorations created another era for science and technology. | |
| Floppy disk drives were originally introduced commercially as a read-only device to hold microcode and diagnostics for large IBM (International Business Machines) mainframe computer systems in the early 1970s. By changing the diskette inside the floppy drive, service engineers could easily update the microcode to the latest revisions or load diagnostics in an easy and timely manner. Diskettes are small, inexpensive, readily available, easy to store, and have a good shelf life if stored properly. But in 1971, Intel introduced the microprocessor or the Òcomputer on a chip.Ó It incorporates most or all of the functions of a central processing unit (CPU) on a single integrated circuit (IC). The first microprocessors emerged in the early 1970s and were used for electronic calculators, using binary-coded decimal (BCD) arithmetic on 4-bit words. Since the early 1970s, the increase in capacity of microprocessors has been known to generally follow MooreÔs Law, which suggests that the complexity of an integrated circuit, with respect to minimum component cost, doubles every two years. Floppy disks and microprocessors both improved the computer systems in the 1970's. | |
| VCR(videocassette recorder) and Atari, a company, also changed the entertainment forever. VCR is a device that can record television programs or the images from a video camera on magnetic tape it can also play prerecorded tapes. A VCR converts the separate audio and video portions of a television or video camera signal to magnetic flux variations to magnetize the tape. The video recording heads move in a direction almost perpendicular to the tape movement, resulting in tracks that run diagonally across the tape width and increasing tape capacity. On the other hand, an Atari is a company wherein they produced the first low-priced integrated circuit TV games. was founded in 1972 by Nolan Bushnell and Ted Dabney. It was a pioneer in arcade games, home video game consoles, and home computers. The VCR and Atari's products both helped define the computer entertainment industry in the 1970's. | |
| Genetic Engineering was also famous in the 1970Õs. Because of this, the first test tube baby, Louise Brown, was produced. On July 25, 1978, Louise Joy Brown, the world's first successful "test-tube" baby was born in Great Britain. At 11:47 p.m. a five-pound 12-ounce baby girl was born. The baby girl, named Louise Joy Brown, had blue eyes and blond hair and seemed healthy. Still, the medical community and the world were preparing to watch Louise Brown to see if there were any abnormalities that couldn't be seen at birth. The technology made her conception possible was heralded as a triumph in medicine and science. | |
| Furthermore, space exploration occurred. On December 07, 1972, 12:33:00 a.m. EST from Kennedy Space Center, Apollo 17, the last manned craft to the moon, brought back 250 samples of rock and soil. Scientific objectives of the Apollo 17 mission included geological surveying and sampling of materials and surface features in a pre-selected area of the Taurus-Littrow region, deploying and activating surface experiments, and conducting inflight experiments and photographic tasks during lunar orbit and transearth coast(TEC). Moreover, July 15, 1975, apollo 18 and U.S. Apollo 18 and the USSR's Soyuz 19 both linked up in space to conduct joint experiments. | |
| Other noteworthy developments of the 1970s included these inventions or innovations: email (1971), first retail barcode scanned (1974), the laser printer (1975), MRI scanner (1977), and the first space lab (USA Skylab, 1973). Many inventions were made in this era that contributed a lot today. Technology is really a big help in our society then and now. It makes the people’s lives easier and more fun. Until today, technology is still evolving and it will never stop. | |
