@AndrewCurran_ Training inside of simulators reminds me of this fantastic work from Ted Chiang: en.m.wikipedia.org/wiki/The_Lifec…

People who run lots of small training jobs for your day job, what is one thing about experiment management / hygiene that you wish you knew when you started out?

Five career tips for mechanical engineers: 1) If it sounds too good to be true, 98% of the time, it is, thousands of clever people spent their lives researching how things are now, incrementally. Success is almost entirely by small steps, and not whacky tricks. 2) We are all VERY stupid, drop your ego, nobody is more despised in an engineering firm than the loud mouth who everyone on the shop floor knows is full of s**t. All you have to be is smarter than you were yesterday, and be happy to throw your calculations in front of everyone for scrutiny. 3) I do not really like the "university" idea in terms of how it has become thought of, getting your bachelors, masters or doctorate is just the start. I can tell you that in nearly every major project I do, I spend sometimes weeks reading the work of other people before I decide I know what to do. Almost never, unless it is a very trivial problem, do I say, "oh I have a degree I know what to do". Every day for the rest of your life is "literature review day". Never does it end, and if you step off this elevator, you can become so lost you may never get back on it again. 4) If you have a very difficult disagreement at work, its up to you to prove you are correct with data and numbers. Even if you KNOW you are right, you must do the work to prove it to everyone else, being right is only the first part of the job, persuading everyone else that your idea is the best path forward is the next part, and if you really CANT prove it, you may have to accept that being right within the confines of your own mind is not sufficient proof in the real world. In other words, if someone else has an inferior idea to you, but explains it with greater clarity, you deserved to lose. 5) If you spend one month, deeply intensively researching ONE specific technical problem, with all your effort, you will find that you graduate to the pantheon of mechanical engineering, where you and a select band of fellow devotees can all gather and agree you still don't know the answer. All you have to do is realise that your worst answer is now better than 99% of everyone else`s answer. You are now to those people who didn't spend that month researching the topic, an "expert". Which is just someone who is wrong to a smaller degree than most people on one specific question. If you can do all these things for years, and work hard, people will start asking YOU for advice, and you will need to remember that "working hard worked", and all the clever nice things people ever said about you, were because YOU worked hard, and never once stopped reading.

At Magdeburg, Germany jahrestagung.gamm.org/annual-meeting…

The 94th edition of the GAMM annual meeting being opened by Prof. Peter Benner.

It is a great honor for me to receive the prize for the Best Doctoral Student (Mathematics) for the year 2022! Many thanks to my Ph.D. supervisors Dr. Lihong Feng and Prof. Dr. Peter Benner (@pebe32), other collaborators, and colleagues at the Max Planck Institute, Magdeburg.

As an academic writing coach, here are the 7 mistakes I see supervisors and PIs make in the process of co-writing a paper with their PhD students or mentees. A thread. 🧵 #AcademicTwitter #PIchat #newPI

@gnu_texmacs The dynamic mode decomposition or, the more general Koopman approach may be of help. Koopman theory in essence says you can express a finite dimensional nonlinear system as an infinite dimensional linear system.

@AldakheelFadi @UniHannover @ga_unihannover @PostdocLUH Many congratulations Prof. Aldakheel !

Our "little" @MPI_Magdeburg group at #SIAMCSE23

This needs to be said!

Hello, I've been using Matplotlib for 7+ years and I still google how to do everything except plt.plot()

@latzplacian Can totally attest/relate to this. IMEX solvers are simple yet highly efficient, especially with nonlinear problems. Have used it often in my work. Colleagues in my group have also used it in gas network simulations to solve hyperbolic problems. @modelreduction

The biggest illusion in academia: life will be more relaxing after this deadline...🤓

I get a lot of reviews that say my work is not novel and I bet I'm not alone. It's always frustrating because I see novelty where the reviewer doesn't. Rather than rebut every critique, I've written a blog post to help reviewers think about novelty. perceiving-systems.blog/en/news/novelt…

@modelreduction This looks like a fantastic tool! Currently using the Xpad post it notes app on Ubuntu; this seems a neater idea.

@matthen2 Read once that the slime mold is able to solve a maze with food particles at the exit; it spreads across the maze filling it and once reaches the food, thins out the other areas while reinforcing the path to the food.

Mammals dream about the world they are about to experience before they are born “Brain circuits are self-organized at birth and some of the early teaching is already done. It’s like dreaming about what you are going to see before you even open your eyes.” news.yale.edu/2021/07/22/eye…
