Khan Academy Presentation Zen Shortly after he returned to Apple in 1997, Steve Jobs gave an internal presentation to employees from the Town Hall building on the Apple campus (YouTube link below). This was an important presentation to let employees know where the company stood and where it was heading. A typical CEO may have put together a slide deck and run through a kind of SWOT analysis. But in this presentation, Jobs —dressed in shorts, sandles and a black turtleneck— stood before the audience and took them on a journey, without notes or slides, where he did touch on Apple’s Strong & Weak points, and also on the Opportunities and Threats, but in a way that was conversational with clear examples. “This is a very complicated world, it's a very noisy world. Jobs then reminds people that Apple is one of the world’s top brands, right up there with Disney, Nike, SONY, etc. “Nike sells a commodity, they sell shoes. • Ideal world: Apple would be growing and its marketing/branding message would be clear and powerful.

Milankovich vs the Ice Ages guest post by Blake Pollard Hi! My name is Blake S. Pollard. I am a physics graduate student working under Professor Baez at the University of California, Riverside. I studied Applied Physics as an undergraduate at Columbia University. I am passionate about physics, but have the desire to apply my skills in more terrestrial settings. Glacial cycles are one essential feature of Earth’s climate dynamics over timescales on the order of 100′s of kiloyears (kyr). Here is a brief summary of some time series analysis I performed in order to better understand the relationship between the Earth’s Ice Ages and the Milankovich cycles. I used publicly available data on the Earth’s orbital parameters computed by André Berger (see below for all references). As you can see, it’s a complicated mess, even when you click to enlarge it! • obliquity (tilt of the Earth’s axis), • precession (direction the tilted axis is pointing), • eccentricity (how much the Earth’s orbit deviates from being circular). where Your First Year in Physics Grad School : Starts With A Bang Teacher Writes on Blackboard: “The Method of Guessing”Student: “What! There’s a method???????”Teacher: “Yeah, there’s even a proof!” -overheard in a physics grad school As a physics professor, one of the challenges I face is how to advise young students nearing the end of their undergraduate career on how to succeed in graduate school in physics. The best I can do is tell them about what I’ve done myself that’s worked for me, and what pitfalls I’ve seen others fall victim to. As an undergraduate, my grades were all over the place. But I did what many undergrads — in many disciplines, not just physics — do. go to class, having not looked at the book or my previous notes,take notes and try to pay attention,and then open up the book, my notes, and the homework assignment the afternoon before it was due, and try to crank the whole thing out. And there was, of course, always an extensive amount of cramming the night before a test. Image credit: Matthias Bartelmann.

UpGoer Your Ph.D. This one type of stuff, which means stuff that always has an interesting field around it, has lots of use in computers and such things. This field changes easily when you do something to the stuff, which means the stuff can be used to sense changes. The stuff will lower another field you put it in quite a lot, so the stuff is good for this if needed. For these things, the stuff is used in very small pieces. In this book, I first tell about my ideas on well-known stuff when grown on top of other stuff. Second, I talk about my studies on edges between two slightly different stuff.
