  • Science is like going down a Wikipedia rabbit hole. There’s always more things to do and more things to check out. At some point you just have to draw the line and say that enough is enough. Other scientists are likely to ask why you stopped where you stopped, and so saying that “it’s outside the scope of the paper” is basically the nice way of saying that you stopped because you felt like it

    It’s very simple - the sun isn’t burning. The sun is actually a very large healing crystal. As you may know, healing crystals capture the harmonic vibrations of the universe and turn them into things that are good for our health, like warmth, vitamins, essential oils, and positive ions.

    The sun is made out of a healing crystal that converts the vibrations into warmth, witch is what we see as sunlight. The sun is so big that it’s able to capture a lot of harmonic vibrations and so it makes a lot of warmth.

    The real question is who polished the healing crystal that forms the sun, and who put it up into space. The natural answer is that it’s clearly done by my good friend Moonlight Namaste, and she will teach you how to do the same thing if you visit her blog and sign up for her meditation classes. With enough guided meditation, you too will start to see the universal vibrations and learn how to change your oscillations to match the universal vibrations. The first 200 people who sign up will get a free dream catcher, so sign up today!


  • Definitely not the same, at least in my experience. It differs by field, but in my field, grad programs basically have zero classes, and whatever classes there are are generally automatic A’s. In turn, the difficulty comes from the fact that you are basically in indentured servitude to your advisor, and there is no actual recourse for trivial things like “overwork” and “burnout.”

    I know of people who did 70 hour work weeks, and for a period of time, I had to do that as well. Also, you get paid less than you would if you had just gotten a 40 hour per week job at a company.

    Anyways, the advisor that you pick really makes or breaks your experience.

    Is it alright to go around wiping the OS off of other people’s computers?

    • is what your comment reads like to me.

    To be clear: each machine generally needs a computer to be permanently plugged into it. Generally the computer belongs to the university. You’re not plugging in your own personal laptop into the machine. Saying to install Linux on these computers is essentially tampering with the university’s electronics and IT will be very unhappy that you did that.

    That’s the thing - in space, orbits don’t decay. Orbital decay only happens if there’s dust or atmosphere that you bump into along your orbit to slow you down. But in interplanetary space, there’s no dust or atmosphere, and certainly not enough to decay your orbit fast enough to achieve results (otherwise, the Earth would have already decayed and melted in the Sun)

    You need to spend fuel to lower your orbit to hit the Sun, and you need to spend fuel to raise your orbit to escape the solar system. It turns out to be really freaking difficult to hit the sun because it simply requires so much fuel to lower your orbit enough to hit the Sun.





  • I find that it’s best to use 65C for the bed temperature for the first couple of layers, and then drop the temperature to 50C. If you’re using Cura, there should be an option to do that, but you’ll need to dig through the advanced settings to find it. Doing this has completely solved warping for me (Ender 3 Pro v1 with PLA filament). My understanding is that it works because the temperature differential between the top and bottom layers causes a pulling force that causes the warping that you see. I think it’s something about the expansion of the plastic due to heat - as the plastic cools down, it shrinks, which pulls the layer below it upward. The wider the base, the stronger the pulling force. And the more layers you add, the more the pulling force compounds, until eventually the print warps.

    The solution is simple - minimize the temperature differential. You really only need it to be hot on the initial layer, for the print to stick properly. And afterward you only need to maintain a temp that’s just hot enough that the print doesn’t pop off. Hence, 65C initial, 50C for everything else afterward

    Probably less relevant, but I also find that adhesion improves if you have the printer go at half speed for the first couple of layers. Again, there should be a setting in Cura, but it’s in the advanced settings

    I find that I can just use these 2 modifications and everything just works. No need for glue. I just dust off the bed when it gets dusty but beyond that, I don’t mess with it. Actually, the adhesion is quite strong. Even after the bed has cooled to room temperature, I have to exert a bit of force to pull the print off the bed

    Scientists can get really petty in peer review. They won’t be able to catch if the data was manipulated or faked, but they’ll be able to catch everything else. Things such as inconclusive or unconvincing data, wrongful assumptions, missing data that would complement and further prove the conclusion, or even trivial things such as a sentence being unclear.

    It generally works as long as you can trust that the author isn’t dishonest
