DNA and the structure of the Milky Way…the greatest female discoveries

Even if many refuse to acknowledge this, the role of women in all fields cannot be denied, and we cannot limit them to the role of the housewife only. There are women who have crossed the limits of the sky with their knowledge, made many amazing scientific discoveries, and have become pioneers in distinctive and very difficult scientific fields. , many men couldn’t even read about it.

Discovery of DNA

Rosalind Franklin

Three men won the Nobel Prize in Medicine in 1962 AD, for their discovery of the genetic fingerprint or double helix, which is the molecular form of DNA, but in fact this discovery was actually made by a woman named “Rosalind Franklin”, who was part of the discovery team, and worked in cooperation With the three men, but they deliberately ignored her efforts, even though she had the first and last credit for that discovery, but they denied it and accepted the award alone. However, Rosalind continued her research, and made amazing contributions to this discovery despite her exclusion from the spotlight, and she was able to… From a close-up photo of DNA, it looked like an “X” in the film, and the photo was later named “Photo 51.” A play was produced about the work of Rosalind Franklin with the same title, whose discovery enhanced our understanding of ourselves and the deeper workings of the body, making It has helped physics, biology and chemistry advance significantly since then.

Discovering the structure of the Milky Way

Heidi Jo Newberg

milky way It is a barred spiral galaxy that contains our solar system, and extends at least 100,000 light-years. Professor of physics, Heidi Jo Newberg, who works at the Rensselaer Institute, devoted all her efforts to studying the structure of the Milky Way, and Newberg and her team found that the Milky Way is devouring The stars are from smaller galaxies. It also found that the Milky Way is larger than previously thought and has more ripples. In 2002, Newberg’s research discovered that the Milky Way’s disk was wavy. This led to a revised estimate of the galaxy’s width from 100,000 light-years to about 150,000. A light year, but scientists are still debating this measurement.

Turn off the light

Lynn Westergaard Howe

Slow light. Did you know that the speed of light can slow down in some cases? This is what we learned thanks to the Danish physicist Lyn Vestergaard Howe, who discovered slow light. In a vacuum, light travels at a speed of 299,792 kilometers per second. However, when light travels through… Matter, it slows down, and by injecting light into something called a Bose-Einstein condenser, Hao and her team at Harvard University were able to slow the speed of light to a mere 27 kilometers per hour, and even more surprisingly, they stopped the light in a Bose-Einstein condenser, which will be mentioned. Howe goes down in history as the first person to actually turn off a light.
