In my last post, I shared a bit of my history with the "Mars Spectacular," and I encourage you to take a look at that if you have not already.

But, alas, I can't just stop at refuting this claim by demonstrating that it's been made before. No, I have to refute it with math!

Read MoreTeaching and grading 12+ hours a day takes a lot out of me, and until that settles down this spring, posts to this website will be (and obviously have been) spotty. But I haven't given up! I have big ideas for upcoming posts and other improvements. I just need to finish grading lab reports, first...

Everything I write here involves learning physics, but it's time to go over some fundamental material that will serve as a foundation for upcoming posts I have in mind and provide much-needed background for one of my earliest articles.

Read MoreI have gotten a couple of requests from family members for me to share my eclipse experience. They are itching to see my pictures and hear my stories, and I have been so focused on school that none of this material has been forthcoming. Until now!

Read MoreNo, dear website, I have not forgotten about you.

It has simply been a busy couple of weeks...

Read MoreIn a recent post, I calculated the \(\Delta v\) of an unladen Saturn V rocket and concluded that the maximum speed of such a vehicle, when launching from Earth, is over \(36,000\,\mathrm{mph}\). As I explained then, that is fast, *but not fast enough for our purpose!* Furthermore, as is typically the case, we want to use our rocket to carry something into space, and the addition of a payload will slow us down even more!

I am busily working on another post called *The Problem with Payloads*, within which I make that claim that for any positive numbers \(A\), \(B\), and \(C\), where \(A>B\), \begin{equation} \frac{A}{B} > \frac{A+C}{B+C} > 1. \label{081117frac} \end{equation}

For an upcoming blog post, I need to know the maximum speed that can be achieved by a Saturn V rocket—for SCIENCE!

Read MoreYesterday, I posted a detailed explanation of the technique of quantum teleportation and hopefully demonstrated that the process is not as complicated as one might expect! *And also that it is not going to lead to Star Trek transporters anytime soon.* No, unfortunately, we will have to settle for a mere quantum Internet instead.

It's been a while, but if you have followed this website throughout the past couple of weeks, then you have (hopefully) learned that

Read MoreIn my previous post, I used my latest invention, quantum playing cards, to give specific examples of entangled and non-entangled quantum systems. I recommend reading that article if you have not already done so, or reread it if it has been a while, for today I am going to expand upon that example and use it to introduce a bit of mathematical formalism, which is necessary for our ultimate goal of understanding quantum teleportation.

Read MoreNot too long ago, I introduced the ideas of entanglement and wave functions with the ultimate goal of explaining quantum teleportation. I also wrote about how I have been too busy to post recently, and how I am therefore anxiously yearning to return to this topic. Since that post, I have been writing as much as I can and feverishly subjecting myself to a crash-course in JavaScript to come up with examples that I think nicely illustrate the basics of quantum entanglement. Hopefully, you will agree and by the end of this post poses the fundamental knowledge necessary to understand this phenomenon.

Read MoreA week has passed since my last post, and to me that is non-ideal. In a perfect world, I would post every single day. A more realistic goal is at least three times a week. Unfortunately, last week I was pretty busy pursuing the necessities of life and seeing to the needs and wants of friends and family. While I am happy to do that, of course, I was all-the-while very anxious to get back to writing and finishing up our investigation of quantum teleportation. After all, there are other topics I wish to explore, such as:

Read MoreI just made a couple of changes to the website which should vastly improve its functionality and user experience.

Read MoreYesterday, I introduced the concept of wave functions, which encode all of the information about a quantum system. Specifically, we can use them to derive the probabilities of different outcomes of a particular experiment.

Read MoreYesterday, I wrote about research in which scientists teleported quantum information from a laboratory to a satellite in Earth orbit. Today, I would like to describe the basic physics of quantum teleportation and explain a few details about this particular experiment.
