The equator is a cool place to encounter physics: you’re moving faster, you’re farther from the center of the earth, and you weigh less. It’s also a common place to encounter pseudoscience: from the Coriolis force to balancing eggs, tourists may be told things they never knew were true… because they’re not. Skepticism is a healthy skill we could all use more of these days.
While in Ecuador this February, we ventured up to Cotopaxi base camp, which sits at 16,000 feet. Having seen the tops of some of the world’s most famous mountains, I already knew about the importance of proper acclimation to high elevations, but it was still a record for us. I also learned some lessons about how the thinner atmosphere can affect camera equipment.
A friend recently warned me against using my electric blanket. While there are established risks (including burns and fires), she was talking about health conditions that could be caused by electromagnetic fields. Hypothesizing about health impacts from environmental exposures can walk a fine line between conscientious public health research and pseudoscience. The difference between the two lies in what we do with answers we get.
Giving up animal products entirely may not be a feasible option for many of us, but more people are eating less meat and cheese – and really making it count when they do. While I may never be a full vegan, it is important to me that I try to match my behaviors to my values, and that means eating less cheese more often.
Physics, cooking, energy efficiency, and public health: so many of my passions are the ingredients of this blog post about our new induction cooktop. Magnetic induction cooking equipment has recently been getting cheaper, more accessible, and more popular, but it has long been safer, cleaner, and more energy efficient than the conventional alternatives, such as gas flames and electric coils.
Like many people, I don’t always take proper care of myself, despite knowing better, and despite encouraging others to do so. In our increasingly tech-centric world, we are developing terrible habits, particularly when it comes to posture, which can lead to short-term discomfort and long-term health conditions that are more serious. Thankfully, those issues can often be addressed (even reversed) with consistent self-care.
Of those who just saw their first total solar eclipse on April 8, 2024, many described to me having a feeling of greater connection to humanity and a broader perspective about how we’re all on this tiny blue marble together. This eclipse (my third) reminded me of that, but also that nothing is perfect in life, but that doesn’t make our limited time here any less precious.
I certainly didn’t notice any news about the global transformer shortage until there was a possibility we would need a new one on the pole outside our house and wouldn’t be able to get it. Demand is exploding for this critical piece of basic technology, but supply will be a limiting factor in how quickly we can bring new renewable energy projects online worldwide.
For some of us, science is like a religion, but the battle between science and religion has been raging for centuries. Hawai’i’s Mauna Kea is sacred ground, but it is also the site of several research telescopes. This situation reveals many difficult questions to ponder, including justifying the cost of scientific progress and determining who gets to make those decisions.
The thing that started this whole road trip was my desire to see my first annular eclipse. Distinct from a total solar eclipse, this “ring of fire” is a strange sight to behold – and that’s coming from someone who travels to see total solar eclipses. Over the years I’ve learned some lessons about what to do (and not) in order to get a good view.
