Author: Gabriela Radulescu, Guggenheim Postdoctoral Fellow, Smithsonian Institution As humans began to explore outer space in the latter half of the 20th century, radio waves proved a powerful tool. Scientists could send out radio waves to communicate with satellites, rockets and other spacecraft, and use radio telescopes to take in radio waves emitted by objects […]
The main ontological thesis of the German philosopher Markus Gabriel could be summed up in the phrase: “the Whole does not exist, but everything exists.” If we replace “the Whole” with a more familiar word (“the world”), the first part of the thesis amounts to the striking claim that “the world does not exist”—a phrase […]

If you’ve ever fallen down a Wikipedia rabbit hole—clicking link after link until you’re far from where you started—you’ve explored a network, much like physicists map connections in systems like the internet or ecosystems. Each Wikipedia article is a dot, each hyperlink a line connecting ideas. This vast web, built by millions of contributors, mirrors […]

We saw in our past entry how the moral philosophy theory known as longtermism is rooted in the historical trend towards ‘the expansion of the circle of empathy’, in order to include all future human beings (or ‘persons’, we might say, including non-human, or post-human persons), and also commented on some flaws of the theory […]
Author: Daryl Janzen, Observatory Manager and Instructor, Astronomy, University of Saskatchewan Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time — the interwoven fabric of space and time at the heart of Albert Einstein’s theory of relativity. Space-time is frequently described as the “fabric of reality.” In some accounts […]
One of the most popular versions today of the idea that there can be moral progress—in the sense that our values and moral standards can keep improving—is the claim, much in vogue now, that such progress takes the form of what’s often called the expansion of the circle of empathy. The idea is that, in […]
If you’re reading this, you’ve probably taken a calculus course before. How was it? Chances are you found it frustrating or, at least, complicated. You may remember one of the most feared parts of calculus courses: the computation of derivatives and integrals. For most students, this is the first time they face a mathematical problem […]
