Procedure to enable wireless LAN adapter in vmware!

I have went to find the way in which wlan in Kali Linux could be made listed my airmon-ng command. Most of the videos and posts suggested me that it is necessary to have another wi-fi adapter to have connected to wifi network. But this is not necessary. The procedure to do this is as follows: 1. Download this package in Virtual Machine(Kali linux) " http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-06-26-p.tar.bz2" 2.Unzip this package in terminal i.e navigate to place where you have downloaded this file , say desktop then type : cd Desktop for unzip type : tar -jxvf compat-wireless-2010-06-26-p.tar.bz2 3. Navigate into the uncompressed directory and type: i."make unload"  (only words within the quotes are the commands) ii."make load" Done!  now airmon-ng  should have the list of the required devices.

Intuitive Way of understanding voltage!

Formal definition in an Electromagnetic course tells us that it is "It is the amount of work done in bringing a unit positive charge from infinity to that point".(definition of potential,voltage is potential difference) So it is basically work , and it is particular form of work i.e of a unit charge carrying work. Well the problem with this is we encounter the notion of infinity here. So infinity is bit paradox in nature. Lets try to get idea of infinity by some metaphor. Lets assume you are ant , but a scientific research ant and ant community is as good as human community. All facilities are to the scale of ant community.The ant present in a garden and mapping of garden and discovering many things and phenomenon in garden is work of generations for ant. So they have no idea of earth, planets or solar system.They would be calling that world beyond this park is infinity, it means the measure is way beyond the potential to measure such thing. All the story gave a perspec

Why cross method of multiplication or vedic method of multiplication works?

It is evident the truth remains eternal even though you have many ways to reach it. With that quote .. So one perspective of the famous vedic method of multiplication can be broken down as follows: let there be two 2 digit numbers  , say       12     and  21   , so writing with their place values, we get (10+2)  and (20+1)  , so if we watch the operation we do in (a+b)(c+d)  is  ac+ad+bc+bd , the same holds good for any numbers. The application of  (a+b)^2 for square of a number is also a simplified version of the above notion. SO the cross multiplication method isn't that spooky , right?
