Need to know Phobos’s orbit around Mars with greater precision? Detect the change in temperature of the Martian soil during a 30-second-long partial eclipse. With a seismograph.

If that paragraph makes sense to you and doesn’t blow your mind, you might be jaded. To me, this sounds like determining the age of a tree by calculating the average number of spots on butterflies in its shadow.

Current state of the world will produce jaded people.

Science is fun.  I spend most of my days looking at noises, which is weird but cool.

You should write up a post about that. Sounds very interesting.

man, that is sexy. I also like the hack folks  did on the Kepler mission after some of it’s reaction wheels failed using the radiation pressure from the sun to keep it pointing in the right direction...

A lot of it is basically using FFT algorithms to break a noise apart into it’s component frequencies and then analyzing those. All my work stuff is proprietary, I can’t share it, but maybe one day I can record a car and see if I can break it down.

It’s easy to forget there has actually been some good news in 2020.

I hate acoustics and FFTs due to the classes I took .... but I mean I still have to use it all in my industry so I guess it’s cool lol

I’ m working on a grad uate degree in acoustics. FFTs galore! I don’t necessarily like it, but at some point you stop hating it and accept it. Fortunately in my job the computers do all the FFTs, we just d o the analysis and interpretation.

Looking at noises... sounds a lot like seismic interpretation.

I’ve described it to others outside the business as a massive ultrasound (since most folks have some experience with one of those, or have at least seen one).

I’m a very positive-minded person, and as depressing as the past several years have been, I see this as just a short dark period that we will come out of soon (clearly, there’s always been lots of “darkness” all over the world if one chooses to focus on it).

That said, if Trump somehow gets four more years, I’m really going to have to work hard to keep up my optimism...

oh yeah onc e we were allowed to use Matlab fft scripts it was much easier to do but understanding is still iffy. Luckily I focused on the mechanical side of things.

I always find ultrasounds awkward. Then again, I’ve had 3 and all were on my private bits. By really cute techs. And Im married. Like I said, awkward.

And I don't do seismic interpretations, I look at man made objects.

Yeah, not as awkward as the first couple ultrasounds a mother has...

Awkward is a really awkward word.

True, but I have no experience with being a mother, n or does Mrs. Snuze. But I can imagine its not fun.

Regard ing wor k, I do underwater acoustics.

Let’s just say that the first ultrasound is... invasive.

Cool!
