About me

I'm a 4th year electonic engineer at Southampton with lots of experience in Electronics, Physics, Maths and computing and am keen to help with any level of these. 

I'm really passionate about technology and physics and from averaging a 1st at uni and with A*'s and A's at GCSE and A-Level I really hope I can help you with whatever you need.

I've loved my past tutoring experiences and hope I can carry this on whether you're struggling a bit or want to really push yourself I can help!

How do you convert from binary to decimal?

Our conventional numbering system is based around the idea that we can represent any number with 10 different digits arranged in a specific order. Because of this, this is called a base-10 or decimal system. In binary, we can represent any number we want with only two different numbers a 1 or 0, so it is called a base-2 system. 

Let's look at an example, first in decimal.

The number 1234 can be broken down into:

1 x 4 +

10 x 3 +

100 x 2 +

1000 x 1

or alternatively

10x 4 +

10x 3 + 

102 x 2 +

103 x 1

From this we can see the evidence of a base 10 system, each time we look at the next digit, we increase the power of the multiplier.

 

So bearing this in mind, we can look at a binary number, made of just 1's and 0's, for example 0110.

Just as above, every time we look at teh next digit, we increase the power of the multiplier BUT binary is base-2...so:

2x 0 +

2x 1 +

22 x 1+

23 x 0

And adding all these numbers up lets you convert a binary number to decimal. So 0110 in decimal is 0+2+4+0 = 6!

Why can't you hear any noise in space?

To understand this, we must first know how sound energy gets from one place to another. This is done via waves, of which there are two different types: longitudinal and transverse.  Light is a transverse wave which travels just like a piece of string would if it was fixed at one end and moved...

To understand this, we must first know how sound energy gets from one place to another. This is done via waves, of which there are two different types: longitudinal and transverse. 

Light is a transverse wave which travels just like a piece of string would if it was fixed at one end and moved up and down at another, and looks like a sine wave.

Sound, however is longitudinal which means energy (sound in this case) moves along by hitting the atoms next to it. These atoms then vibrate and hit their neighbours and so on. Eventually these vibrations reach our eardrum and start vibrating that which is how we hear. 

Space is a vaccum meaning there are no particles to vibrate. If nothing can vibrate then no energy can be transferred meaning no noise!
