This looks awesome. The popup-help&#x27;s are a little jarring though since there&#x27;s no indication as to which words will trigger a popup. Also:<p>&quot;Oh come on, you should know what a vector, v, is by now. Check out Chapter 2, for crying out loud.&quot;<p>seems kind of harsh to say to the reader while they&#x27;re reading the first sentence of Chapter 2..
