Meet your instructor

My name is Jamie Foster and I’ve been immersed in the world of science for over a decade. I completed my PhD in physics at a top university, where I published research on quantum physics and nanotechnology.

Since then, I’ve dedicated my career to translating complex scientific ideas into engaging content for the everyday reader. My goal with this blog is to satisfy your curiosity about how the world works by breaking down key concepts without losing the wonder and excitement of science.

From subatomic particles to the vast mysteries of the cosmos, I hope my writing opens your eyes to the universe. Let’s explore the wonders of science together!

Common Questions

Gravity is one of the fundamental forces of physics. It’s the attraction between two objects with mass. The more massive an object is, the greater its gravitational pull. Gravity controls the motion of everything in the universe from stars and planets to apples falling from trees. According to Einstein’s Theory of General Relativity, gravity is caused by the warping of spacetime around massive objects. The presence of mass curves spacetime, and this curvature generates the force we experience as gravity. The closer two objects are, the stronger the gravitational pull. Gravity keeps us anchored to Earth, causes tides, and allows planets to orbit stars. It’s the force that formed galaxies and galactic clusters. There are still mysteries about how gravity works on quantum scales, but ongoing research aims to unite gravity with the other fundamental forces.

Dark matter is the name astronomers give to an invisible substance that makes up about 27% of the universe. Its existence was proposed to explain discrepancies between the mass we can see in galaxies and the stronger gravitational force we can measure. Normal matter like stars and gas only accounts for about 5% of the universe’s mass-energy. The rest is dark matter and dark energy. We know dark matter exists because of its gravitational influence, but it doesn’t interact with light or normal matter except through gravity. That makes it incredibly hard to detect. Dark matter appears to clump around galaxies and cluster together shaping the large-scale structure of the cosmos. Some theories propose dark matter is made up of an exotic unknown subatomic particle. Discovering its identity is one of the top priorities in physics. Understanding dark matter could provide insight into the nature of matter and forces.

Vaccines work by training your immune system to recognize and fight off infectious pathogens like viruses and bacteria. They contain weakened or inactivated pieces of a specific disease-causing microbe. When a vaccine is introduced, your immune cells analyze these foreign invaders and start producing antibodies tailored to mark them for destruction. Memory cells are also created so your body can quickly deploy these antibodies if the real microbe enters. This primes your adaptive immunity to be ready for future exposure. Vaccines safely build immunity without you having to get sick first. Some vaccines require multiple doses over time to boost and reinforce the antibody response. Vaccines have revolutionized public health saving millions of lives. The COVID-19 pandemic demonstrated how essential vaccines are to controlling infectious disease. Ongoing research aims to develop new vaccines against diseases we still can’t prevent like HIV and malaria.

Weather arises from the complex interactions between Earth’s atmosphere, oceans, and land. Solar radiation heats the surface and drives convection currents in air and water. The spin of Earth deflects air flows leading to storms and circulation patterns. Mountains, forests, cities, and more all influence local weather. Meteorologists monitor current conditions like temperature, humidity, wind, and pressure across geographic regions. They feed these data points into atmospheric models based on physics and thermodynamics equations. This generates a simulated forecast of how weather systems will move and evolve. Accuracy decreases the further out the prediction, so forecasts are constantly adjusted. Meteorologists also launch weather balloons carrying instrument packages high into the atmosphere to get direct measurements. Advances like weather satellites and supercomputing power are revolutionizing forecasting abilities. There are still challenges predicting the severity of extreme weather like hurricanes and tornado outbreaks. But increased understanding of weather physics and finer resolution models continue to extend how far out useful forecasts can reach.

The brain has a remarkable capacity to store vast amounts of information over decades as memories. Exactly how it accomplishes this feat is still not fully understood, but neuroscientists have shed light on memory formation and storage. When you experience something new, electrical signals pass through neural circuits linking sensory input to processing regions. The hippocampus plays a key role consolidating short-term memories and connecting them to long-term storage regions in the cortex. Layers of cortical neurons seem to store related memories together as an ensemble. The more you recall a memory, the stronger the neural connections get. Some memories like skills and habits involve the basal ganglia. But the hippocampus integrates contextual details into cortical storage. Synaptic plasticity facilitated by neurochemicals allows neural connections to be strengthened, weakened, or remodeled as memories form. Advances in imaging brain activity patterns are bringing us closer to unlocking secrets of our mental filing system. Understanding memory function could transform how we treat cognitive decline and learning disabilities.
