So if a human or other living thing were exposed to gamma radiation, the waves could move so fast that it could pass through them and scrabble their DNA, causing serious mutations and other health issues.

This means that the waves themselves are not made up of anything, they don’t have mass and they don’t have particles, but they still move with energy.

The light passes through the telescope, hitting the first curved mirror, which acts in the same manner as the first glass lens, condensing the light. Then the light hits a second mirror, which reflects towards a glass lens for the viewer.

Light moves in a wave-like pattern, constantly moving through space, and moving through the telescope. But when the object that you are trying to see is so far away, it is difficult to actually see the light it's giving off. So the telescope has a special lens, which refracts and adjusts the light waves to make it more streamlined. This basically means that the lens is condensing the waves to make a clearer, more narrow image. At a certain point the light focuses, before enlarging out again, since it has been bent to the greatest extent it can be by the first lens. Finally, the light waves expand outward a little more before passing through a second lens, which makes the image perfectly clear for the viewer.

She loved the outdoors from an early age, and dreamed of visiting Africa. Unfortunately, Goodall was unable to pay for college so she instead went to secretarial school, where she learned how to type and bookkeep. She took on various jobs in order to save for a trip to Africa in 1957. In Africa she began studying chimpanzees and primates under paleontologist Dr. Louis Leakey. A few years later, Dr. Leakey and Goodall started a new research project at Gombe Stream National Park. There Goodall connected with several chimpanzees, who allowed her to watch them and develop somewhat personal relationships with them; she is credited as the first human to ever be accepted into chimpanzee society. From this experience, Goodall published her first book My Friends, the Wild Chimpanzees, in which she described how chimpanzees were much more similar to humans than previously thought. They were able to build and use tools, something that had defined human intelligence. Fellow scientists were outraged about her methods, stating that her personal connection with the ‘subjects’ of her research inflicted bias on the results. Yet, Goodall continued her work. She founded the Tchimpounga Chimpanzee Rehabilitation Centre in 1992, which fostered over one hundred orphan chimpanzees. Two years later, Goodall established the Lake Tanganyika Catchment Reforestation and Education AKA the "Take Care" project, which aims to reforest deforested chimpanzee habitats and also educate the wider Gombe community about sustainability. Jane Goodall’s research and advocacy greatly expanded and redefined what we considered to be ‘distinctly human’ characteristics, changing our understanding of ecology and evolution forever.

She attended St. Paul’s Girls’ School before attending Cambridge University for chemistry. Her excellence in science allowed her to conduct research at the university, however the second World War put her work on pause. During the war she pivoted to studying carbon and coal to assist in the war effort. This research earned Franklin a doctorate from Cambridge in 1945. Franklin then moved on to work at the State Chemical Laboratory in Paris to study x-rays. Through this research she was able to explain how graphite was made from different processes with carbon, continuing to support the coal industry. Her x-ray research didn’t just benefit the coal industry though, she was able to apply it to the study of DNA as well. Franklin joined the Biophysical Laboratory at King’s College in London in 1945, using x-ray diffraction to analyze the structure of DNA. By assessing it under this method, Franklin could determine both the density of DNA, as well as its helical structure, something that had never been proven. Today, the famous shape of DNA is almost normalized since we see it so often, but at the time this discovery was groundbreaking. Unfortunately, Rosalind Franklin died quite young at only 37 years old on April 16, 1958 due to cancer. At the time she was researching the DNA and RNA of bacterial viruses, which were also extremely new topics of study. Although her lifetime was short, Franklin accomplished much and left a long lasting imprint on multiple scientific fields.

He moved to Florence to study painting and sculpting under Andrea del Verrocchino Despite, who was considered a master of the arts. Da Vinci went on to sculpt and paint some of the most famous High Renaissance masterpieces, including The Last Supper and the Mona Lisa. However, da Vinci was much more than a simple artist, he was also a polymath. A polymath is someone whose knowledge spreads across multiple different subjects. Da Vinci had a strong affinity for science and engineering, partially due to his earlier interest in human anatomy for his sculptures. He designed prototypes of several ‘flying machines,’ including parachutes and helicopters. In addition, da Vinci sketched ideas of a large crossbow, an armored car (now known as a tank), a canon and a car. More impressively, he also wrote about the idea of concentrating solar energy as a power source. Leonardo da Vinci was an extremely important and significant figure during the Renaissance period, progressing the fields of anatomy, sculpture, civil engineering, military technology and astronomy.

Gravity is a downward force that acts on all objects on Earth. The more heavy or massive the object is, the greater the gravitational force on that object. This means that the extremely large rocket of Apollo 11 had a very difficult time getting off the ground. https://www.stempowers.org/blog/katherine-johnson monthly 0.5 2024-11-21 https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/deb56cfa-51f1-4c48-ad92-5342335b3c8a/katherinejohn.jpeg Blog - Katherine Johnson - Katherine Johnson was born on August 26th, 1918 in West Virginia, USA. She was extremely gifted in math, flying through course work at an early age, which allowed her to enter highschool at the age of 10. However, the United States was still largely segregated at this time, forcing her family to commute out of their city to give her an education. After graduating from highschool, Johnson went on to attend West Virginia State College, a historically African American college. At this time, she was mentored by several professors and doctorate holders due to her ability to solve difficult computations. After graduating from college at 18, she became a teacher and then attended graduate school at West Virginia University, where she was the first African American female student ever. Later, Johnson got a job at NASA as a ‘human computer,’ solving math problems by hand using data from planes and aircrafts. Around this time, President John F. Kennedy had set the goal of sending a man to the moon, pressuring NASA into the Space Race. https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/ef6b6a8f-67bf-4f42-a228-bd67a867daef/Katherine+Johnson+-+NASA.jpg Blog - Katherine Johnson - In 2015, President Obama awarded Johnson the Presidential Medal of Freedom, the highest achievement a civilian can obtain. In addition, several NASA buildings, the Katherine Johnson Independent Verification and Validation (IV&V) Facility and the Katherine G. Johnson Computational Research Facility, were named after Johnson due to her immense contributions to the agency. Johnson’s story is inspiring to many around the world, overcoming the tremendous obstacles of segregation, racism, and sexism and leading a successful career as a mathematician. Johnson died of natural causes in 2020 at the age of 101.

Humphry Davy of Great Britain experimented with batteries, wires and a piece of carbon in 1802. The power of the battery traveled through the wires, causing the carbon to glow and produce light. This principle was then replicated in the experiments of various inventors. https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/0805111d-2dc0-41b8-b6a6-3996c294a849/lightbulb+edison.jpeg Blog - The Invention of the Lightbulb - In 1878, Joseph Swan produced a light bulb using carbonized paper filaments. This meant that the paper was placed in the center of the glass bulb, and as power ran through the carbon, it would light up. His bulb was also a vacuum, meaning there was no oxygen or gas floating around inside the glass. This meant that the carbon paper wouldn’t ignite or degrade, since oxygen ‘feeds’ fires and, in this case, would cause the filaments to break down. Swan consistently faced issues with his vacuum system, which posed significant setbacks.

Her love of marine biology drove her to attend Pennsylvania College for Women and then John Hopkins University for graduate school. She went on to work at the US Bureau of Fisheries, where she helped to produce several essays and brochures. Carson’s writing was enjoyed by many, with her work being published in several magazines. She decided to pursue writing further, producing several books with critics’ acclaim. Around 1945, Carson uncovered the issue of DDT, a widely used pesticide destroying ecosystems across the country; yet, the government was funding the programs actively spraying the chemicals all over. To save the wildlife she held dear, Carson wrote Silent Spring, a detailed and gripping book about the destruction DDT caused to the environment. Due to her previous successes as an author, Carson’s newest release sold like wildfire. The country began calling for a DDT ban, and further research on the pesticide’s effects. President John F. Kennedy created a special task force to ‘fact-check’ Carson’s claims, which concluded that Carson had told the truth. The government started to push out pesticide regulations, and with it came the creation of the Environmental Protection Agency (EPA) in 1970. Carson unfortunately died in 1964 due to cancer, before seeing the fruits of her labor. https://www.stempowers.org/blog/microbiologist monthly 0.5 2024-11-21 https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/1719710627889-JI96FL3GJZQGTGZSYKMB/image-asset.jpeg Blog - Microbiologists - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.stempowers.org/blog/the-atomic-model monthly 0.5 2024-11-21 https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/4605a08d-f106-47ea-b545-7411eb2f020b/billball.png Blog - The Atomic Model - The idea of an atom was first proposed by John Dalton in 1803, who realized that all matter was made up of smaller particles or units.

Based on Thomson’s model, he expected the alpha particles to go straight through the gold foil, which most of them did, but some wound up more than 90 degrees from the foil.

She was educated by private tutors in her youth, and as she grew older sought out higher education. However, women were unable to attend university at this time in England (and many other countries). Despite not being able to attend school, Lovelace’s ambition and interest in engineering and machinery propelled her to teach herself the various subjects. She focused specifically in mathematics, and was assisted by Augustus De Morgan, a University of London professor. After she married, Lovelace was introduced to Charles Babbage, who wrote The Analytical Machine, the first proposed modern computer. Lovelace translated the proposal and published her own ideas of how this ‘machine’ could compute difficult equations. This cemented her as the first computer programmer. https://www.stempowers.org/blog/category/Example+1 monthly 0.5 https://www.stempowers.org/blog/category/Example+2 monthly 0.5 https://www.stempowers.org/blog/category/Example+3 monthly 0.5 https://www.stempowers.org/blog/category/Stem+Careers monthly 0.5 https://www.stempowers.org/blog/category/Stem+Stars monthly 0.5 https://www.stempowers.org/blog/category/Stem+History monthly 0.5 https://www.stempowers.org/cookies daily 0.75 2024-05-20 https://www.stempowers.org/our-story daily 0.75 2025-04-19 https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/1745071945036-MBYHH8AHSCGNCZH60SML/unsplash-image-CgIFBwOkApI.jpg https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/1745072122115-AY7O48I6SVGZ9H420EPL/unsplash-image-TJxotQTUr8o.jpg https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/a63229a2-ad84-45cc-b319-b82ed6c08b49/top-view-of-school-supplies-scattered-on-yellow-ba-2023-11-27-05-21-36-utc.jpg https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/6787d920-2e4c-4bd6-8992-a58358300f7a/tempImage8QGmC4.jpg https://www.stempowers.org/privacy-policy daily 0.75 2024-10-31 https://www.stempowers.org/home daily 1.0 2024-10-30 https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/7c5aa53d-ba43-4edf-9716-f9a63eacf48b/Screenshot+2024-08-10+at+2.07.48+PM.png https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/7c5aa53d-ba43-4edf-9716-f9a63eacf48b/Screenshot+2024-08-10+at+2.07.48+PM.png https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/7c5aa53d-ba43-4edf-9716-f9a63eacf48b/Screenshot+2024-08-10+at+2.07.48+PM.png https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/a66099aa-8353-4553-b203-894d9bd24e4e/three-little-students-on-chemistry-lesson-in-lab-2023-11-27-05-14-56-utc.jpg https://images.squarespace-cdn.com/content/v1/664b810f5935ce7ced7df9d2/cfffed3b-3b06-4b5d-b626-045424d4bd52/science-learning-and-research-with-child-in-labor-2023-11-27-04-52-12-utc.jpg https://www.stempowers.org/404 daily 0.75 2024-05-20 https://www.stempowers.org/terms-and-conditions daily 0.75 2024-11-05 https://www.stempowers.org/contact daily 0.75 2024-10-30 https://www.stempowers.org/thank-you daily 0.75 2024-05-20 https://www.stempowers.org/videos daily 0.75 2024-11-25 https://www.stempowers.org/videos/v/hcar39r4zgt9t79dhg7e2p42s83rar monthly 0.5 2025-03-16 https://www.stempowers.org/videos/v/83gtrcahe5ncgghjw4mnetry5lxz2w monthly 0.5 2025-03-16 https://www.stempowers.org/videos/v/yar9d6pbxzyg3jssb9d86ees4ecwrg monthly 0.5 2025-03-16 https://www.stempowers.org/videos/v/catapults-a-lesson-in-physics monthly 0.5 2024-11-24 https://www.stempowers.org/videos/v/roman-arches-a-lesson-in-physics monthly 0.5 2024-11-24 https://www.stempowers.org/videos/v/polymers-a-lesson-in-chemistry monthly 0.5 2024-11-24 https://www.stempowers.org/videos/v/a-lesson-in-circuitry monthly 0.5 2024-11-24 https://www.stempowers.org/videos/v/the-principles-of-coding monthly 0.5 2024-08-10 https://www.stempowers.org/videos/v/parachutes-a-lesson-in-physics monthly 0.5 2024-11-24 https://www.stempowers.org/videos/v/hosted-with-custom-z9ehj-dwh9x-tdlly monthly 0.5 2024-08-10 https://www.stempowers.org/videos/v/planet-earth-mejnx-d2a8y-dl7r5 monthly 0.5 2024-08-10 https://www.stempowers.org/videos/v/everything-to-sell-anything-427ge-88xsk-7b2y4 monthly 0.5 2024-08-10
