A day on April 8th, 2024
“Allen, look! the Robot No.2 holds a plate of corn cakes and some water, standing there, and… seems like walking towards us.” Felix shouts in a low voice.
“Are you sure? Felix, our room is too small, I had a nightmare last night. So hungry now…” Allen opens his eyes gradually and say.
“I am pretty sure. Last time, I was grabbed by him. His upgraded alloy legs are very strong and flexible, like a human. If I have that kind of legs, I will never be trapped here. The Robot No.2 is receiving some commands now. Really hope to eat a full meal otherwise I will starve to death too.”
“You have repeated your story for more than 100 times. I do not care how you come, I just wonder how we die.”
“I appreciate that you can remind me this joke from more than 20 years ago. Shh~, be quiet, he comes.” Felix says again.
The current education system is challenged much more than ever before. Just plan to make an attempt to get myself involved using spare time. Any thoughts are welcome. The knowledge is also for myself.
- Basic math
- Calculus (derivative, integral, etc…)
- Conservation Law (transportation equation)
- physics of fluids
- Finite difference method in 1D->2D
- Finite volume method in 1D -> 2D
- Finite element method (CPR) in 1D -> 2D
- Shock capture
- Others (to be modified)

A book named Deep Work: Rules for Focused Success in a Distracted World by Cal Newport intrigued me recently. It is not like a traditional inspirational book (心灵鸡汤 in Chinese), instead, it attempts to formalize and explain the reasons as well as the strategy of deep work in neurological, psychological and philosophical scopes. In this highly distracted world, countless emails, instant messages, and tighter social connections will destroy our consecutive time into many small chunks. To thrive in the coming digital and intelligent revolution, the author, Cal Newport, suggests us to embrace the depth instead of the connectivity. His idea sounds like technophobia for me, so I can not totally agree with him, but some questions puzzles me a lot after reading that book, which I will go over with some of my immature thoughts at the end.
On June 5-9 2017, I participated in the AIAA Aviation 2017 Forum, which is really amazing. Thousands of scholars/scientists/engineers from all over the world came together to Denver, CO to present their research and also share their opinions. The topics cover every aspects of the aviation science and technology. The most exciting and open-minded topic is to foresee the future of CFD and how to achieve it. In university, I always think that the CFD is already in somewhat mature status, we just need to invent some new parts to replace with the corresponding old parts in the entire CFD ‘building’. However, after I read the paper by P.R.Spalart and V.Venkarakrishnan , I become more objective and calm. It says “We perceive a danger of overconfidence and under-competence in CFD” and “We believe the community must find a balance between enthusiasm and rigor”. I realize that there are still tons of obstacles in front of us to overcome. The role of CFD in service is still very limited.
