The perfect presentation …….or maybe not!!!
Choose a background that doesn’t distract and makes it easy to see the text Choose a background that doesn’t distract and makes it easy to see the text
I said, choose a background that doesn’t distract and makes it easy to see the text choose a background that doesn’t distract and makes it easy to see the text
Either change the font colour
Or, change the background
Or make the whole thing simpler…. Light coloured fonts on a dark background are easily read even at small sizes like 20 point
Or, use a light background which allows the use of… various dark coloured fonts which are easily read even at small sizes like 20 point
That’s why are EXIT signs green on black? Or red on white? Or white on green?
OK, now add a logo which gives your organisation some free advertising …maybe not so big!
That’s better! Now we can concentrate on you and your presentation
Use a font style (eg Arial) which is appropriate. Scientific type presentations don’t go well with some styles which are more suited to advertising agencies
One of the most destracting things for the audience is poor speling. There is no exuse for this since your spelcheker should allert you in most cases.
Proof reed your slides carefully or, better still, have someone else check your presenation to avoid pubic humiliation.
By the way…. To maintain your professional credibility, make sure you use the correct word, eg “Complimentary” or “complementary” “practise” or “practice” “affect” or “effect”
If you use animations These can assist In emphasising a point But don’t overdo it! Because it becomes distracting Or the message Will be lost in the technology Got that?
Illustrations help to maintain interest but don’t make them too small otherwise the audience won’t get the message
Greater impact is achieved by good pictures Kalgoorlie Super pit Union Reefs Tailings Dam Kaltails tailings dam
Your presentation will be out of this world! Hubble image of comet impact on Jupiter Hubble photo looking back 15 billion years
Why bother putting in information which cannot be read easily? All you can do is apologise!
By all means, use images scanned from other sources but note that the quality may not be all that great.

Keep graphs simple to illustrate the point you are making Bad!!!!
General trends are what you are aiming to show
This may be OK for a specialist audience.
This may be just a little too hard to read!!!
But this may be more appropriate for a general audience
This is a presentation not a publication!! Keep the mathematics simple. Developing a Systematic Heat Balance Model Enthalpy balance around any process unit: where molar enthalpies are defined thus: and where molar heat capacities typically take the following form: where a, b, c, and d are empirical constants. Upon integration:
And things like this should never be seen! (but they have been)
Develop your argument gradually. One concept at a time is good. For irreversible reactions involving a limiting reactant: Reversible reactions (e.g. precipitation reactions) are much trickier Subject to thermodynamic constraints Best solved iteratively
Final summary should be brief. The following will take too much time. The fine material has a slower relative leach rate than the coarser particles The overall leach rate is a domain diffusion control The leach domain is determined by the retained moisture determined by the fines The model developed describes the leach rate changes well The model functional form is the same when developed from two approaches Any leach model must take into account the poorer relative leaching of the fine material Without progressive data care needs to be taken in applying the analysis technique Further work is needed to identify a normalisation technique to allow comparison between various top sizes Blah, blah, blah!
And don’t forget your acknowledgments My thanks to my colleagues who have provided the source material for much of this presentation. In order to avoid embarrassing them, no names will be mentioned.
