PWN E095- Halloween 2016
For transcript, links and pictures, check out pwnphysics.blogspot.com Imaginary Numbers: What the heck is it really?? How can a number be imaginary?? Well friends, let me tell you, on this Halloween Night, they are real. There are INDEED numbers which are considered imaginary. They have very special properties which do not exactly line up with what one might consider the “conventional” theory of mathematics, but is now so embedded in it, that it matches theory to a T. Quantum Mechanics cannot be described without imaginary numbers. So what are they?? Well, imagine this. What is a square root? A square root is a number which, when multiplied by itself, equals another number, it’s square. So, the square root of 4 is 2. 2 multiplied by 2 is 4. The square root of 16 is 4. 4×4 = 16. Numbers whose square roots are a whole number are referred to as perfect squares. Now, let’s consider this. Consider negative four. -4 times -4 = 16. So, the squar [...]

PWN E093: BNL Summer Sundays Pt. 3
So this is the third in a three part series about my excursion to Brookhaven National Labs to tour their facilities for 4 “Summer Sundays” Sessions that took place during the month of July. If you’re just tuning in, I encourage you to go back to PWN E091, just two episodes before, and start there, to get up to speed. We’ll be here when you get back. It’s kind of weird, but there was definitely something that kept me coming back to BNL this summer. Again, this time, the kids were in tow, so the main attraction, the tour of the RHIC, or the Relativistic Heavy Ion Collider, was off the table, but I didn’t care. There’s just something about the atmosphere and attitude of this place that I had to get my fill while I could. So what was available, you ask? Well, first on the docket was a trip to the cafeteria. It was at this point that I passed a table where, apparently, if you attended 3 of the 4 weeks, you were [...]

PWN E092- BNL Summer Sundays Pt. 2
So this is the second in a three part series about my excursion to Brookhaven National Labs to tour their facilities for 4 “Summer Sundays” Sessions that took place during the month of July. If you’re just tuning in, I encourage you to go back to PWN E091, just one episode before, and start there, to get up to speed. We’ll be here when you get back. So, this time, when I went, I brought my mom and my friend who were visiting, and my 2 little kids. Because of this lineup, I didn’t hit the lecture. When we got there, first thing we did was go to the cafeteria and hang out over there. Lovely nice open space, with a very friendly staff. Everything at this place is so laid back I love it. And the prices are very reasonable as well. I guess this is where the employees go to eat, so they try and keep the prices down. From there, the purpose of this week was to feature their synchrotron light source. This system creates lig [...]

PWN E091- BNL Summer Sundays Pt. 1
So this is the first in a three part series about my excursion to Brookhaven National Labs to tour their facilities for 4 “Summer Sundays” Sessions that took place during the month of July. So, one thing that I found out last year is that you are not allowed to go onto the BNL campus without authorization. I stopped by and asked if I could drive around, and I got a very stiff “no” from the security guard. I did not realize the gravity, no pun intended, of this facility. BNL is a very serious science research facility. They do classified level research, have a particle accelerator, and at any given time are trying to be hacked by someone. Security is paramount, and so for obvious reasons they don’t want me driving around in my minivan to see the sights. However, for 4 glorious Sundays a year, you can visit and tour parts of this magical place and see what the scientists are up to, in very broad strokes. The first weekend is called [...]

PWN E090- Vectors Virtual Tour and App Launch Party!!
Dig deeper at pwnphysics.blogspot.com Pick up the app in question for only $1.99 at: https://itunes.apple.com/us/app/pwn-physics-vectors/id1081806363?mt=8 The wonderful day is finally here! We’ve come a long way and are finally finished with how to handle vectors. Let’s wrap up by going through a tour of the new app. The first thing you will come across is the welcome screen, and then the main menu which will direct you through everything you need for your introduction to vectors. The first place you want to start is answering the question “What’s a Vector?” Tap this to enter the what’s a vector menu. You can then get detailed explanations for the following: What’s a Vector?

PWN E089d- Linear Examples Pt. 4- The Graph
Dig deeper at pwnphysics.blogspot.com In today’s episode we continue digging into examples concerning our linear equation y = mx+b, where m is the slope, and b is the y-intercept. Our fourth example involves finding the equation from a graph. As usual, coffee-stained notes below. Enjoy!

Dig deeper at pwnphysics.blogspot.com In today’s episode we continue digging into examples concerning our linear equation y = mx+b, where m is the slope, and b is the y-intercept. Our third example involves some not-so-nice numbers, to show how it usually is in math, ugly numbers. Find the equation of a line with slope -0.36 and intersects the point (271,25). As usual, coffee-stained notes below. Enjoy!

PWN E088: Anatomy Of A Line
So, last episode I had mentioned a really great article which mentioned how it’s currently possible to see 5 planets in the morning sky. Well, this weekend, I had a chance to check it out and managed to see Venus, Saturn, Mars, and Jupiter in the sky! Check out the pics below. On to the line. In this episode we dig deep into the three major “anatomy points” of a line: the slope, y-intercept and x-intercept. The slope: The “angle” of the line. From 0-45, the slope [...]

Episode 086b: Vector Anatomy
Dig deeper at pwnphysics.blogspot.com 1: The Vector- The arrow in magenta is the vector in question. Everything else in the image serves to describe this vector. It’s represented as an arrow and can be slid anywhere in the coordinate system and still retain its properties: the magnitude and direction. 2: Y-Axis- The black vertical arrow represents the y-axis in our coordinate system. This gives a reference point for all of the vectors in our system. 3: Origin- Most physical systems only make sense when [...]

PWN E086a: How To Get Unstuck In Physics
Dig Deeper at pwnphysics.blogspot.com How To Overcome Getting Stuck In Physics Recently I’ve been working on an app. Which one doesn’t really matter. It’s about a topic that I really enjoy and I’m excited about it. In working on it, it has easily been the hardest app I’ve ever developed, although absolutely nothing about it is different. In general, my apps follow a formula, because they are modular; they deal with different sections of physics and offer a very similar solution. First, understand the topic. Next, break that topic into easy, doable, step by step solutio [...]

PWN E0085a- Wardenclyffe Tower Pt. 3 & Newton’s Birthday
Dig Deeper at pwnphysics.blogspot.com I went back to Wardenclyffe Tower! Not much has changed since last I went (check out episodes 029 and 30 for the original Wardenclyffe pilrimage), except all of the conifers were decorated for the season. I also noticed a plaque with many Tesla pictures under plastic, including the classic photo of him with the light bulb, as well as several pictures of the original tower. I can’t wait until this place opens for real. I hope I’ll be able to go decorate one of the Christmas trees there next year. So, during the “On this day in physics” section of PWN Physics 365, I wish a happy birthday to Issac Newton, born 04 January 1643. I post the episode, and then during my internet travels, came across a tweet from Neil Degrasse Tyson from Christmas which very cleverly alludes to the birthday of a very special man who will change the future of humanity, only at the end of the tweet [...]
