 This book is the product of more than six decades of leadership and innovation in
physics education. When the first edition of University Physics by Francis W.
Sears and Mark W. Zemansky was published in 1949, it was revolutionary
among calculus-based physics textbooks in its emphasis on the fundamental principles
of physics and how to apply them.

The success of University Physics with
generations of several million students and educators around the world is a testament
to the merits of this approach, and to the many innovations it has introduced
subsequently.
In preparing this new Thirteenth Edition, we have further enhanced and
developed University Physics to assimilate the best ideas from education
research with enhanced problem-solving instruction, pioneering visual and
conceptual pedagogy, the first systematically enhanced problems, and the most
pedagogically proven and widely used online homework and tutorial system in
the world.

Modern Physics, 3rd edition - Kenneth krane

 

This textbook is meant to serve a first course in modern physics, including
relativity, quantum mechanics, and their applications. Such a course often follows
the standard introductory course in calculus-based classical physics. The course
addresses two different audiences: (1) Physics majors, who will later take a
more rigorous course in quantum mechanics, find an introductory modern course
helpful in providing background for the rigors of their imminent coursework
in classical mechanics, thermodynamics, and electromagnetism. (2) Nonmajors,
who may take no additional physics class, find an increasing need for concepts
from modern physics in their disciplines—a classical introductory course is not
sufficient background for chemists, computer scientists, nuclear and electrical
engineers, or molecular biologists.
Necessary prerequisites for undertaking the text include any standard calculusbased
course covering mechanics, electromagnetism, thermal physics, and optics.
Calculus is used extensively, but no previous knowledge of differential equations,
complex variables, or partial derivatives is assumed (although some familiarity
with these topics would be helpful)

Q) What is an ip address?
A) An Ip address is a label assigned to every device connected to a network or internet.Any device connected to internet could use this label to connect to another device connected to internet.




Types of ip addresses :-

1) Dynamic ip : These types of ip are always changing. Mostly broadband connections have these type of IP. These are assigned automatically by your ISP.

2) Static ip : These ip addresses don’t change. They remain same. You either had to buy one from your ISP or sometimes it comes free with your plan.


3)Public ip : Public ip address makes your device accessible to other users of internet. Anyone on internet can connect to your server using your PUBLIC IP.
To check your Public IP visit :
whatismyip.com

4)Private ip: Private ip is an ip address assigned to devices on a private network like computers present in your school/college have different Private ip address. It is used to communicate between computers on a Private network connected using hub/switch or any other way.
To check your Private ip :

a)Open cmd .
b)Type ipconfig and hit enter.
c)The number shown against Ip Address is your Private ip.


You could assign Private ip on your own by :-
1)Double click on network connection icon in taskbar.
2)Click on Properties.
3)Click on internet protocol(tcp/ip).
4)Tick on “use this configuration”.
5)Enter your details.
6)Click on Ok.

Example scenario:
1) Let us suppose a computer Lab A in a school containing 20 computers all connected to each other using a switch and connected to a Modem[ all 20 to a single modem].
Then their *Private ip* address could be checked at cmd via point 4). This *Private ip* is mostly *STATIC* .
But their *Public ip* will be same as they are connected to internet via same route ie same modem. This *Public ip* will be assigned by the ISP and may or may not be *Dynamic*.


2) Let us take another computer lab B with same configuration as lab A. Now let us suppose computer xyz. It will definately have a different *Public Ip* as compared to Lab A, but it may or may not have same *Private ip* as that of any computer in Lab A.
There is one more thing, two devices could never have same Private ip connected to a same network. But two devices connected to different network may or may not have same Private ip.
This mean two computers either from lab A or B, both could have same *Public ip* but can never have same *Private ip*.

Example Explained :
Xyz computer From lab A:
Private ip : aaa.bbb.ccc.ddd [Generally STATIC]
Public Ip : xxx.yyy.zzz.www [Anything assigned by ISP, could be *DYNAMIC* or *STATIC* depending on your subscription]

abcd From Lab B
Private Ip : eee.fff.ggg.hhh [this could be same as Private IP of XYZ in Lab A, Generally STATIC]
Public Ip : qqq.eee.www.ttt [This could never be same as that of lab A, anything assigned by ISP, could be *DYNAMIC* or *STATIC* depending on your subscription]

Now Enjoy it, stay connected and share link on Facebook, Twitter, Google Plus etc.

5 Top Windows 8 Features You’ll Love

5 Top Windows 8 Features You’ll Love

Following the release of Windows 8 Developer Preview, many sites have done reviews on what the next Windows system will be like. The reviews are mostly positive, with some hailing Windows 8 as the next revolution in the technology of computer operating systems (OS). Such may well be the ambition of Microsoft, and it shouldn’t surprise time it comes at a time when Apple’s share of the OS market is rising and pitting fiercely against them.




If there’s one thing great about competition, it is that it brings out the best product between companies. I’ve read up some of the features that Microsoft’s Windows 8 will be offering, and am now both intrigued and excited for what’s to come in the full version. It will even come with a new and unique kind of user interface (UI) known as the Metro.

Here are brief descriptions to some top features you would be keen to know about:


1. Speedy Boot Time

The load and boot up speed has improved significantly over Windows’ predecessors. This is partly due to the better resource allocations to applications and the system. When compared to Windows 7 desktop CPU, Windows 8 has an even speedier boot time.
How did they improve so much over Windows 7? Well, Windows 8 employs a technique of hibernating the system kernel (think of it as your OS’s resource manager) when you shut down, such that it becomes almost like a partial hibernation each time. When you reboot the system, the ‘memory’ of your previous session gets reinitialized quicker.

2. Innovative & Dynamic Desktop

The tiles-based interface, or the Metro UI, will be the first thing you see upon logging in to Windows 8. At first glance, the UI seems to go intuitively with touchscreen devices like tablets and smartphones. Indeed, in such devices, you tap on those apps to open them. The grid layout seems to facilitate such interactions. Needless to say, you can customize your grid by adding and arranging applications.
The coolest thing, however, is that not only does Windows 8 allows you to personalize your desktop with the organization of the apps, it is also able display real-time information through them. Microsoft had demonstrated how the tile for a weather app could reveal the current temperature in a city without having to activate the app. The same goes for emails and such. In one glance over your tiles, you can have access to all that you need to be notified and take action on those which are urgent.

3. Improved Search Function

8 has no search box at the bottom of the Start menu. Heck, it doesn’t even have the trademark Start menu! That doesn’t mean that there’s no convenient search function available. All you need to do is to type anything, and a search box will appear from the right and give you the results. The search capability is even stronger this time, displaying all the matching apps and files instantaneously.
You can also search within apps that utilize Windows 8′s search function. The search pane that pops out on the right of your desktop will contain the list of apps which you can conduct the search in. For instance, if you’re looking for the emails sent by a particular contact, typing that name and clicking on the email app would allow you to search from within.

4. Windows To Go

Of the entire list here, this is one feature that offers the most convenience to users. Windows To Go allows users to make a copy of their OS complete with their settings, wallpapers, files and even apps, into a USB thumb drive. Plugged it into another computer with Windows 8 already installed, and you can boot up the PC and make it look exactly alike the OS you normally use, with all settings intact.
It sounds rather amazing, doesn’t it? The potential for such a feature is high and possibilities, many. For one, a virus-infected and crashed system could be revived by simply plugging in the USB thumbdrive with your last saved settings, inclusive of all your files, apps, etc. Users don’t have to worry about losing the ability to work on their projects just because their PC is down; they can always rely on plugging in that thumbdrive into another Windows 8-installed PC. Another is that users may simply bring back work from the office with that thumbdrive rather than a much bulkier laptop.

5. Windows Live Syncing

Similar to Windows To Go, the new Windows 8 will provide Windows Live syncing, such that users can login on any Windows 8 PC with ‘Live ID’ and get back their own personalized settings on it. The desktop will look the same every time the user login on a PC with their Windows Live account. Migrating to a new PC is probably made easier when the user has all the essential settings synced.
How different will this be from Windows To Go? Well, Windows To Go seem to serve more as a controlled device for IT administrators to distribute to employees (with exact duplicates of Windows 8 with the same settings, wallpapers, apps, etc on thumbdrives), while Windows Live Syncing is more to allowing users to keep the basic settings and data available even if they’re away from their primary PC. We can only anticipate how the former and latter will be truly be like until they are unveiled by Microsoft in due course.
