One thing you may have noticed about the trigonometric functions sine and cosine is that they seem to have no agreed upon definition. Or rather, different authors choose different definitions as the starting point, mainly based on convenience. This isn’t problematic or even particularly unusual in mathematics - as long as we can derive any of the other forms from any starting point, it makes little theoretical difference which we start from since they’re all equivalent anyway.| www.oranlooney.com
R, like many scientific programming languages, has first-class support for complex numbers. And, just as in most other programming languages, this functionality is ignored by the vast majority of users. Yet complex numbers can often offer surprisingly elegant formulations and solutions to problems. I want to convince you that familiarizing yourself with R’s excellent complex number functionality is well worth the effort and will pay off in two different ways: first by showing you how they a...| www.oranlooney.com
Official Copy: Final report of Doug Engelbart's in-depth study on augmenting human intellect and human effectiveness: a unifying framework for what makes us collectively capable and effective, a design strategy for systematically improving this capability, and proposed research agenda. Early research results include these pioneering firsts https://engelbart.org/Firsts. Serving as his guiding vision throughout his career, this report outlines a call to action still relevant today.| www.dougengelbart.org
