Thanks for the suggestion, but I don't think that's exactly what I'm looking for. Elevate seems similar to general "Brain Training" apps like Luminosity where it's really just memory games and such. I'm essentially looking for the Duolingo of math.

I noticed that this thread was moved from the Math forums to Computing..I don't think this was the right move. Regardless, beginner to intermediate/advanced. Something more difficult than the basic arithmetic found in the apps that were returned in the search results that seemed to be geared...

I was browsing the Play Store early this morning looking for a quality app that would allow me to practice and learn various mathematic topics on my mobile device. Surprisingly, none of the results were very good. There were a few basic "flash card" type applications with basic arithmetic, and...

Great suggestions, thank you. That Antony Jameson presentation is quite interesting, i'll be sure to look it over.

Very cool. I've nearly completed a book on the Pegasus engine, this looks like a good supplemental read. Will give that a read, thanks!

Very interesting, thank you. When you say some of the most computationally intensive tasks are structural analysis, I assume you mean tasks like finding the max loads/temperature that something like a compressor blade could withstand, correct? What other components might you perform structural...

I did not ask about slide rules because my research is focused on the usage of computers in jet engine design. You're more than welcome to talk about how slide rules are used when designing engines. You asked: I would use them for writing articles, essays, a letter, a book, and so on. Using...

No, I asked the following:

When designing, building, or testing a jet engine, for what tasks would you need to use an analog computer to solve a differential equation or equations involving time based transients?

How were analog computers used for design/testing? I gave a short presentation on the history of jet engines..ranging from the He 178 (worlds first turbojet powered aircraft) and Frank Whittles contributions, to later century fighters and bombers, to modern jet airliners using efficient...

Was there no intermediate step between no computers and CAD software being used? I would have assumed early designers may have used early computers to compute complex calculations during the design or testing phases, such as calculating aerodynamic properties.

Then help me narrow it down. For example, the GE J79 turbojet used on the B-58 hustler, F-104 and the F-4 Phantom II was originally produced in the mid 50s and continued production through the 1960s. Given that CAD software like CATIA wasn't available till nearly the 1980s, or SolidWorks until...

Hello all, I have been tasked with writing a very short article regarding the use of computers and software in early jet engine design up to modern times. I've been having a relatively hard time finding reading material through Google. I understand that modern jet engine designers use CAD...

There isn't, unfortunately.

Hello PF, I built a small application which I figured some users here may be interested in. The app aggregates news and events in the space industry, allows you to view launch schedules, track the space station, and more. It's called Luna and an early version is available on the Play Store...
