Fine-Tuning of the Universe: The Anatomy of a Scientific Mystery

How is it that the universe’s parameters are “just right” to support life? Can science ever solve this mystery? In his book A Short History of Nearly Everything, Bill Bryson discusses a few of the unknowns and controversies that still exist in the sciences. One of those is the “fine-tuning problem.” Continue reading to learn about the fine-tuning of the universe and why it has many scientists scratching their heads.

Is a lot of mass unaccounted for in the universe? If so, why? Where is it? When author Bill Bryson set out to understand the great scientific discoveries about our universe, he ran into some unsolved mysteries. One of them is the missing mass problem, and he discusses it in his book A Short History of Nearly Everything. Keep reading to learn about missing mass, including the question of whether the mass is actually missing or whether the current theory is off.

How Old Is the Planet, and How Do We Know?

How Old Is the Planet, and How Do We Know?

How old is the planet? How do scientists estimate the age of the earth? What assumptions are part of the calculation? In the middle of the twentieth century, scientists developed a system to help them determine the age of rocks. This, along with an assumption about the formation of the solar system, allowed them to estimate the age of the Earth. Keep reading for an exposition of the Earth’s age.

Informed Decision-Making in Healthcare: How to Assess Outcomes

When you’re making medical decisions, what do you consider? How do you evaluate your options? Medical decisions are some of the most important decisions you make. Neuroscientist Daniel J. Levitin argues that you shouldn’t try to intuit such decisions because your brain just isn’t good at it. He recommends using a fourfold table to analyze the information you’re working with. Continue reading to learn how to use this process for informed decision-making in healthcare.

The Interior Parts of Earth: What’s Down Below the Surface?

How much do we know about the interior parts of Earth? What are the current theories? Contrary to what you’ll see in sci-fi movies, nobody’s been to the center of the Earth. We can dig only so deep. So, scientists have to resort to some indirect ways of determining what’s far below the Earth’s surface. Continue reading to learn what scientists believe and why.
