Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

With regards,

8th Std - Mathematics - 29 April 2024

Do you have school going children ?

 

If yes, here is how you ( and your spouse ) can help them with their studies


Whenever they have difficulty grasping a study-subject, tell them to consult this

VIRTUAL TEACHER :

www.HemenParekh.ai


Just show them how to “ Ask “ a question to this teacher , using their Mobile –

and get immediate answer


If they do not like to “ type “ , then they can simply “ talk “ to

www.HemenParekh.ai


Virtual Teacher will “ talk back in my ( synthetic ) voice – as shown below !


This is far better than consulting ChatGPT – Bard – Gemini – Perplexity – Ask QX

etc., all of which can chat with your child , only in English


Her Virtual Teacher  can “ Chat “ with her in EnglishHindiGujaratiMarathi

BengaliTamilTeluguKannadaMalayalam  !


For children of our far flung village schools ( approx. 13 lakh schools in 6.4 lakh

villages - most with just ONE teacher ) , there is nothing which comes any closer

to a Virtual Teacher ( in a manner very much similar to how the statue of Guru

Dronacharya teaching archery to Eklavya )




Regards,
