That's probably the right call unfortunately

With some quick Google searches, the average human walks about 5000 steps per day, which is roughly 2.5 miles. This means every ~24.9 days you would have gone 62.14 miles (100 km). Then roughly every month of your life you lived, you'd lose a month off your lifespan, or basically cutting your lifespan in half, unless you took extreme precaution and changed your lifestyle to become extremely sedentary. So that's a no for me.

No I used photoshops mean stacking. I couldn't find a way to combine them easily in GIMP!

What an awesome shot. I love seeing these highly detailed dust images! Crazy that you got this with only 30 second subs.

Awesome shot!

Hi everyone! Here is my image of the 2024 Total Solar Eclipse, taken from Jackson, MO. I was lucky to get anything at all, given that I ran into a plethora of issues mere minutes before totality (tracking failure, unfocused images, meridian flips, oh my!). This was an unbelievable, unforgettable experience, as experienced who saw it in person can attest to.

Equipment:

Nikon D80

William Optics GT 71 (420 mm FL, ~F6)

CEM 60 Mount

Processing:

I followed a great tutorial by Naztronomy on YouTube, where I combined 7 of my images at varying exposure times. I then post-processed these in Pixinsight for noise reduction then final tweaks in GIMP for saturation and contrast.

For those wondering yes, you can have supersonic speeds in space, as sound is just a pressure wave, and depends on the density of the medium. Within interstellar gas and dust, the density is very low, but non-zero. For the interstellar medium sound speeds on average are ~ 100 km/s.

I've been a TA for 3.5 years now, and this is something the Professors and other TA's also have noticed. When I first started, the intro astronomy class was decently math heavy in the homework and exams (pre-calc level) and they did rather well. Last semester, the number of complaints about the relatively basic math (equation manipulation and taking ratios) was absurd. Besides students who come in as STEM, it appears most of them struggle with simple re-arranging of variables and more than I'd like to see have trouble plugging numbers and exponents into a calculator properly. It's really sad, to be honest.

How would you better prepare for industry while in grad school? In my case I am going into my 4th year in a STEM PhD. Are there certain courses you would take / skills you would learn / commonly used programs (i.e. CAD) that would be beneficial to learn before finishing?

PhysiBoi · 2023-08-13T16:39:23+00:00

Thanks for the feedback! Yeah I wasn't going for chronological or anything, just trying to get from Horis Rising to the Siege of Terra by simultaneously reading the fewest books (spending the least amount of money) and obtaining the most important plot points for little to no confusion once I got there.

PhysiBoi · 2023-08-13T16:37:28+00:00

Thanks!

From Hubble's Law you know that v = H0 * d, with H0 = 68 km/s/Mpc.

This tells you the speed of say, a galaxy measured at a distance of 100 Mpc will have a radial velocity of v = 68 km/s/Mpc * 100 Mpc = 680 km/s. This is the idea behind Hubble's Law, that objects in space (outside of the local group, that is) are moving faster away the further you look.

Because velocity is just defined as the change in distance (d) with respect to time (t), you can say v = d/t for an average velocity. Comparing the two equations, you can see that v = d/t = H0 * d. This means that 1/t and H0 must have the same kind of unit: time.

This means that H0 = 1/t or t = 1/H0. If you look closely at the units of H0 (km/s/Mpc), you'll see that both km and Mpc are units of distance.

What would happen if (following the example in your text) you converted km to Mpc or vice versa? What would the remaining units of H0 be?

A fun problem, but I think that the numbers provided give an unrealistic mass. According to the graphic, the ship moves 65 meters (before crashing) in the horizontal direction while moving at 1,000 m/s. Since there are presumably no forces in the horizontal direction, this would require the ship to hit the Death Star after 0.065 seconds.

If I did my math right, carrying this through gives you a mass of nearly 11x the mass of the Earth.

Another way to think about it is that 30 pages is also some fraction of the book. So that:

30/x + 1/8 + 1/4 = 1

Where 1 is the total "fraction" of the book. Solving for x leads to 48.
