How did Perseverance Slow Down?
First of all, what did Perseverance need to accomplish to be successful? Well, it had to slow down from 12,100 mph to zero in the span of seven minutes, so that the rover wouldn’t completely explode upon reentry.
The Internet of Things
What if your fridge could order milk when you were running low? What if the lights could check your calendar and make an appointment with the electrician to be replaced? What if the devices in your home could “talk” to each other in a way that made your life safer, happier, and more efficient? This is exactly what the Internet of Things aims to do.
We can fly!
Planes are incredible! They can fly thousands of feet into the air and weigh 90,000 pounds! But somehow, they manage to stay up in the sky and transport people, animals, and goods around the world. Have you ever wondered how this is possible?
Genetic Mapping: Navigating the Human Genome
Efforts to advance understanding of the human body and each of its intricate components have provided groundbreaking information, slowly unraveling the complexity of our most essential systems and facets. The Human Genome Project (HGP) is an international campaign focused on establishing the base pairs that make up human DNA.
Classes of Organic Molecules
The body has 4 general classes of molecules: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are simply sugars. The smallest type of sugar, like glucose, is called monosaccharides. Disaccharides are 2 monosaccharides combined. An example is when glucose and fructose is joined together to form sucrose, a disaccharide. A polysaccharide is a chain of monosaccharides.
