Hearing about the death of a woman due to the failure of her iron lung inspires both sadness and respect. Being forced to live within an iron lung from almost when she was born because of polio, it is awe-inspiring that she still managed to live a fulfilling life despite her almost claustrophobic environment. It is sad that such a woman had to die because of the simultaneous failure of the normal power grid and the emergency generator.
This makes me think how good it is that polio has almost been wiped out. Otherwise we would have many more people who would have to live in such a restricted condition, ranging from being paralyzed to having to rely on an iron lung. Considering that this is thanks to vaccines, I find it incomprehensible that some people are against vaccination because of their bogus belief that it can cause autism.
It might be different if there were any evidence for such a belief, but when multiple high-quality studies show no link between vaccination and autism, they're just trying to spread suffering and death from disease. I have no idea if this is out of malice or out of stupidity. While it's my nature to assume the latter, their vitriolic persistence in their belief despite strong evidence to the contrary sometimes makes me suspect the former.
If you like photography, then Tips from the Top Floor is a nice podcast to listen to. It has a rather cozy feel to it, in that the podcast is very community-driven, and it often gives out nice tips and background knowledge that budding photographers can appreciate. The semi-regular Tech Guy episodes, which are actually recordings from a separate radio show done with also the host of the Tips from the Top Floor podcast, are also great for learning basic photography techniques and other tidbits.
Audiobooks are like podcasts except much longer. They're actually books read aloud by a narrator. Like podcasts, they're nice for when you aren't able to sit down and read a book but would still want something to "read". Unlike podcasts, however, they're a bit harder to pause and resume listening at a later date.
This is really cool: NASA has managed to photograph the image of a spacecraft descending on another planet. The Mars Reconnaissance Orbiter managed to take a picture of the Mars Phoenix Lander as it was descending with its parachute deployed. While the image is not sharp at all, it's really impressive when I think of what it's showing.
If you want to learn about astronomy, Astronomy Cast is a great podcast to listen to. It's a podcast that introduces the general public to diverse topics in astronomy. It not only explains what we know about astronomy, but how we know about things in astronomy (paraphrasing their slogan).
When it first started, I thought I would not learn anything new since most of the topics were those that I had read or heard about before, but I was pleasantly surprised when it turned out that the podcast goes deeper into things without making things difficult.
