.mat to .avi conversion bugs

Animations and Modelling are the order of the day for Earth Atmospheric Scientists. Matlab movies although visually pleasing sometimes end up being a trouble maker. It is not difficult to create a movie out of 50 images in Matlab. But what makes it challenging is to retain the same fps(frames per second) after we convert .mat to .avi or .mp4 file. When i did this, my fps spec in Matlab had no impact on the .avi file i had created. 2 frames per sec or 10 frames per sec appeared the same when the .avi file (created in Matlab) was played in media player. Neither did media player allowed me to change the fps. If you are thinking to regenerate them using any other movie format, forget it! Decoders can go wrong anywhere ! So, buckle up! Here we go heading towards the solution! Microsoft GIF animator. Import your file, select all images in the left, change to animation tab , specify the repeat mode-->switch to image tab--> wow! there it is-! change the number of frames per second, width, height and you are done! Insert into MS-PPT- as sweet as a nut! I'm not sure if this is a Matlab bug. Any other suggestions from readers are most welcome! Thanks in advance! Enjoy Modelling!

Speaking of DNA science ....

What would it require to think like Einstein or be a charismatic pioneer like Steve Jobs or solve the half length puzzle left by Leonardo da vinci? In other words, how would it be to inherit a glorious life of our ancestors (some hundreds of years back) who were once stalwarts in different fields? Before you read ahead, pause... and ponder... 'Is it plausible to argue from modern bio sciences perspective that we can bring back the genetic cognitive skills and unique potential of the ancestors in their present generation'?

I was perfunctorily flipping through a you tube clipping on the movie '7am Arivu' on a busy monday night. I took a break to see if there is something interesting happening in Kollywood. As I was watching this movie, I mulled over the above question for a while and my answer was No. I said to myself, such strategies can turn true just for a two hour science fiction movie.

A day after, I realized I was wrong. It was so surprising to hear about a pionering research field in stem cells and life sciences that actually focus on DNA activation to reshape an individual's cognitive skills and personalities such that he can retrieve any unique feature which his/her ancestors had in the past. Also, these stem cells are capable of re-activating a part like Brain cells which usually dont show signs of growth unlike other parts in the body. These techniques are being researched to solve medical questions on Brain-death, Coma etc. Isn't that amazing? Thanks to Navneetha for an interesting chat on this technology. Good to see a film conveying a scientific message in Kollywood after a long time.

I was bullied and harassed on Facebook.

Online harassment and gas lighting are fearful experiences that many of us struggle to speak in public. I recently got verbally abused, thre...
