Why are PDFs sometimes so much larger than the original? I thought they were supposed to be compressed (e.g., I have a 4.4 MB .pptx that has become a 25MB .PDF).
PDFs are notpressed overall they are files ding various objects. Some of those objects can optionally be encoded using a number ofpression schemes eg gzip or JPEG but it is not required by the standard. A native file format is pretty much guaranteed to be smaller it is structured and only needs to be understood by the application which uses it. So it could include nothing more than gantt chart with 24 columns and that sufficient for PowerPoint to render the entire thing. PDFs can also be very small. A document can be reduced to simple vector primitives and and those can further bepressed. For some applications which natively produce PDF output it can lead to very small file sizes smaller than the original. However most applications output PDFs using a printing pipeline. These are not optimised for file size but forpatibility they often rasterise much of the content as a high quality as a PNG even though it was originally a JPEG). Alternatively they can output a great deal of information which isn visible like hidden layers or entire s (which may be lossy). Often these can dramatically reduce the file size but by how much depends on how the PDF is constructed.

A plane consumes much more fuel during takeoff than at any other time. (For a 1.8 hour fight the MD8 burns half of the fuel required for the fight from takeoff to level off. Fuel flow on takeoff roll is about 3 lb Fuel flow in cruise is about 13 lb) I feel a speaker cannot go wrong by devoting a similarly high ratio of energy and planning to a strong opening italic . It is worth thinking that your speech actually begins well before you start speaking indeed before you even get onto the stage. Your audience will be judging you evaluating you from the minute they set eyes on you and know that you are the speaker. n How you walk up to the stage how you gather andpose yourself before your first words how you energize yourself and the audience before your first words matter significantly.

Will this opening Introduce the topic? Establish some connection and rapport with the audience? Have the audience thinking Keep going don stop tell me more? Be constrained between 5%31 % of the time?
