I first started using WhatsApp as a medium in 2014, when it was new, to connect with my MBA students with the passed out MBA students to understand their workplace and to understand the practical application of what they study. It did work out and also had other activities happening as the concept was new then.
Dear Shoban, thanks for your valuable comments and contributions, on World Academies (WAC) not only the profile content and the individual interests of the users are important, but also the group activities (academic/technical/scientific/training) are also very much important for our users, to experience group discussion, team working and group learning, which have been the key points of human civilization progress. We would like to thanks WAC group leaders establishing interesting and powerful groups, and WAC users and experts whom participate and support group working activities.
Sure Social media is playing a Significant role in Education and in other fields..
Very nice topic Mehrdad, it is true, this means that high qualified social media with better scientific contents are needed, then we may invite professor Holden Thorp to World Academies (WAC).
why not!
Then try for it, send an invitation, or let me know his contact info to be invited. I thin this can be an important approach on WAC to invite some famous scientists, artists and influencers that care about educational content of the social media pages.
At 18:00 today, Friday, Berlin time, there will be a running parallel video conference describing How to create WAC group
very well. thank you very much.
It’s wanderful👌
Dear Prof, Thank you so much.
We are progressing very well.

Then you can setup your simulation case better, perform more meaningful analysis, and enhance your creativity for preparing your results as new manuscript, patent developments and new projects.
Dear Sir,
Hope you are doing fine. I have a question. After enrolling the course, is it possible to have the recording? Cause, there are a lot of students who wants to take the course, however, their classes ends at 5 or 6 pm. What’s your comment on that? Is it possible to shift the time a little bit so that students and professionals can also take the course?
Regards
Dear Kawsar, yes the full lectures will be recorded, and the video will be available quickly after the course in the working group of the Machine Learning for the registered participants, for 6 months after the lectures are finished. Then the participants can join the lectures and also use the recorded video if for some sessions have timing problem.
What is the level of the course? Is it advanced, medium, or intermediate?
This course is for beginners and intermediates. The advanced course will be announced for the lectures on January to May 2024.
Good Day Aliyar,
I’m interested to join the online sessions because they will help me a lot with my master thesis. I’m studying CO2 switchable surfactants in an attempt to evaluate different surfactants in terms of their foam generation and stability. However, I think it’s late for me at the moment. I would like to ask you if the lectures recorded or the presentaion slides available. Would it be beneficial to me if I joined now?
