In other words- when did someone say: "ok, now it's 12:00 pm, we are counting from now on, set your watches?,,,"

I hope I made my question clear...

I am trying a lapping technique for the first time, and I don't want to buy the suppliers special "blotting paper storage notebook" until I know the films will work. I have not found blotting paper in my local stores. Is there a low-cost alternative that you use? And, how durable are lapping films compared to polishing cloths, in your experience? Thanks, in advance.

If suppose each living thing on this planet is a recieving 'device', meaning all that we see around us are nothing but signals transmitted to the 'brain' by all our senses-eyes,ear,mouth,skin,nos... So the whole world is just an image formed in our brain made by these signals. So even our brain, body everything is just an image formed in that recieving 'point'. We cannot even be sure if all of our 'past' was just fed into us at one single moment, or if it really did exist.How can we know for sure that the world really exist or if we are 'something' stationary and just that the signals are continuosly being fed into us?The dream state gives more proof for this, coz even in a dream we can feel, touch, hear, smell and see our body someplace else(a different world),which actually doesn't exist in reality!And what happens when we r in deep sleep- no senses,no world, no people-nothing!

I found this to be a bizarre concept, but couldn't find anything to prove it wrong either. What do u think
