Lovecraftian horror is a unique type of terror that responds to the rapid scientific progress of our era, using scientific elements to lend eerie plausibility. Rather than recognizable monsters or graphic violence, the terror in Lovecraft's fiction lies in what's not directly portrayed, but left instead to the dark depths of our imagination. Lovecraft's protagonists often stumble onto hints of the existence of the Great Old Ones, beings that exist beyond our conceptions of reality, whose true forms are as inscrutable as their motives. Even indirect glimpses of them are enough to drive them insane. The Cthulhu Mythos, named after Lovecraft's infamous blend of dragon and octopus, is a shared universe adopted by a wide variety of authors, often reimagining them from diverse perspectives that transcend the author's prejudices. Learning about Lovecraftian horror will inspire you to independently explore academic topics through reading, reflection, writing, and self-directed projects.

Teflon, a material that doesn't stick to anything, was stumbled upon accidentally in 1938 by a chemist named Roy Plunkett. Teflon's properties make it perfect for things that need to be slippery, chemical-resistant, or waterproof, which means it has a lot of applications. It can be found all over the place, from raincoats to industrial ball bearings to artificial joints. The incredible properties of PTFE, the chemical name for Teflon, come from its molecular structure. It's a polymer, meaning it's made of long chains of repeating units of atoms strung together. PTFE has tight carbon-fluorine bonds that ignore the normal, intermolecular forces that help substances stick to each other. Even the famously adhesive feet of geckos usually can't get a grip on it. Learning about the properties of materials like Teflon can inspire independent exploration of science and engineering, which can lead to exciting career opportunities in fields like materials science and chemical engineering.
The future of resource extraction lies in space exploration. Asteroids, leftovers from the formation of the planet 4.5 billion years ago, contain rare and precious materials such as platinum, iron, and nickel. The mining industry on Earth is harmful to the environment and people, but space mining could provide a clean and sustainable alternative. Cheaper space travel is necessary to make asteroid mining profitable, and scientists and economists are working on solutions such as electric spaceships. Once a stable asteroid is secured, space mining and processing equipment can extract valuable materials through a process that uses giant mirrors to focus sunlight and heat up asteroid rock. Even a small percentage of a single asteroid's mass in precious metals could be worth billions of dollars. The benefits of space exploration and asteroid mining are vast, and the possibilities for discovery and innovation are endless.
Maps are a fundamental tool for navigation and education, but did you know that every map humans have ever made is wrong?

Glass is a material that we use every day, but have you ever wondered how it works? Glass is made from silicon dioxide, which is heated until it becomes a flowing liquid. As it cools, the molecules lose energy and become an amorphous solid, allowing light to pass through without being scattered. The subatomic level of glass is what makes it transparent, as the electrons in glass are spaced far enough apart that visible light can't provide enough energy for them to jump between them. This unique property has made glass an essential material for many uses, from windows to lenses. Understanding the science behind glass can help you appreciate the importance of this material in modern civilization.

The desire to transcend the limits of our mortal bodies has been a theme in human stories for centuries. With the rapid advancements in technology, the idea of uploading our minds into a digital utopia is becoming more plausible. Mind uploading and digital immortality are core themes in the game Cyberpunk 2077, which explores the possibilities and implications of this concept. But is it really possible? Mind uploading is based on three assumptions: that the mind is in the structure and biochemistry of the brain, that we will understand the brain well enough to simulate it, and that computer software can host the mind. These assumptions are still being debated by scientists and philosophers. Understanding the brain's complexity is essential to exploring this topic, and while we have a basic understanding of how neurons and synapses work, there is much more to learn. Despite the challenges, exploring the concept of mind uploading is an exciting intellectual pursuit that could have practical implications for our future.
