![]() ![]() ![]() I personally have used Notability on an iPad, which I found quite effective. Most people I know (myself included) vastly prefer this option for generating hand written PDFs. However, if you have an tablet (iPad/Android) or touch screen laptop (mostly Windows 8 like the Surface), there are many software options that allow you to create PDF slides by writing directly on the screen with a stylus. Hand-writing slides most likely will not be consistent.Īll of these distract the audience thus hindering your ability to convey the message.Īs Stephen Kolassa mentioned, using a writing tablet or scanning notes are both options. Difficult to maintain consistency: PowerPoint, Beamer or Keynote allow you to write slides with a consistent structure (e.g.Difficult to format: unless you use topographic tools, hand-writing slides will have elements mis-aligned and improperly formatted.Difficult to read: hand-writing is always more difficult to read than computer font like Helvetica, Arial or Times.Difficult to maintain: if you need to re-use a slide in a future presentation, you will suffer If you try to change then in a hurry (e.g.If you believe that someone may ask for more details, just add an extra slide in the end with the full derivation, or just say (the technical details can be found in Ref. Instead, use words to describe how you got there ("using the approximation X, the assumption Y and Z, we can derive "). Put an equation on a slide using the same reasoning you put a graph: only if it is really worth to fully explain it. My advice is: do not trow equations to the slides just because they are part of a demonstration or something. If your presentation is good enough, those specialists will read your paper anyway and will be able to follow the derivation on their own pace, along with all the technical details.Įquations are extremely useful because they summarise an extraordinary amount of information, but because of that, they are also difficult to read, understand, and digest. This is because no audience will follow the technical details of a derivation anyway, except probably for 1 or 2 specialists. Unless you are deriving a simple result as E=mc^2 on a slide, on which the derivation itself is beautiful and is thus part of the message, there is only one reason to have a slide full of equations: when you want to convey that your result was non-trivial to derive and that this slide is not supposed to be understood by anyone in the audience. What message you want to convey on each slide?. ![]()
