Equipped with the right applications, a computer can be of great help in virtually any domain of activity. When it comes to designing and precision, no other tool is as accurate as a computer. Moreover, specialized applications such as AutoCAD give you the possibility to design nearly anything ranging from art, to complex mechanical parts or even buildings.
Suitable for business environments and experienced users
After a decent amount of time spent installing the application on your system, you are ready to fire it up. Thanks to the office suite like interface, all of its features are cleverly organized in categories. At a first look, it looks easy enough to use, but the abundance of features it comes equipped with leaves room for second thoughts.
Create 2D and 3D objects
You can make use of basic geometrical shapes to define your objects, as well as draw custom ones. Needless to say that you can take advantage of a multitude of tools that aim to enhance precision. A grid can be enabled so that you can easily snap elements, as well as adding anchor points to fully customize shapes.
With a little imagination and patience on your behalf, nearly anything can be achieved. Available tools allow you to create 3D objects from scratch and have them fully enhanced with high-quality textures. A powerful navigation pane is put at your disposal so that you can carefully position the camera to get a clearer view of the area of interest.
Various export possibilities
Similar to a modern web browser, each project is displayed in its own tab. This comes in handy, especially for comparison views. Moreover, layouts and layers also play important roles, as it makes objects handling a little easier.
Sine the application is not the easiest to carry around, requiring a slightly sophisticated machine to properly run, there are several export options put at your disposal so that the projects itself can be moved around.
Aside from the application specific format, you can save as an image file of multiple types, PDF, FBX and a few more. Additionally, it can be sent via email, directly printed out on a sheet of paper, or even sent to a 3D printing service, if available.
To end with
All in all, AutoCAD remains one of the top applications used by professionals to achieve great precision with projects of nearly any type. It encourages usage with incredible offers for student licenses so you get acquainted with its abundance of features early on. A lot can be said about what it can and can't do, but the true surprise lies in discovering it step-by-step.

History

AutoCAD started out as a series of bitmapped graphics primitives, which were made available in the first release of AutoCAD. In 1982, a survey was done by a group of Autodesk employees (the design staff) to see if users of their own design staff would appreciate something similar. They produced a series of sketches on a blackboard. All the sketches were in the same basic colors, but there were some variations in the type of line, curve, and fill. This particular series is known as the “Blackboard Series” or “BBS”.

The first working version of AutoCAD was called Release 6. A blue screen, with three icons, was shown on the screen. The screen was very similar to what was seen on the early Apple II computer. The first of these three icons (named “D”) was labeled “DRAW”. The second icon (named “DRAW” or “DRW”) was labeled “DRAWW”. In 1982, when Autodesk released the first AutoCAD version, the first screen (or “Frame”) showed the second icon, labeled “DRAW”. It was only after the 1983 release of AutoCAD that the third icon, labeled “DRAWW” was added.

The very first files for a working version of AutoCAD were written by Paul Boedeker in February 1982. Paul developed the files to be able to handle functions that had not yet been written into the graphics controller at that time. Paul wrote many of the graphics applications while working at his first job at Autodesk, at the Science Research Systems Corporation (SRS). The most important graphics applications written by Paul were the initial versions of the command line editing (CLI) of commands, DXF file I/O, and a primitive graphics library.

The next version of AutoCAD, Release 7, was released on January 31, 1983. The first published version of Release 7, which was available to the users of Release 6, included 3D type primitives such as, circles, ellipses, lines, squares, and polygons. The polygon was created by using a line segment to create a polygon. In addition, Release 7 had closed shapes that could be drawn, such as boxes and ovals. Release 7 also included a feature called Drafting Preview. This was the first drawing capability that allowed the user to see how the drawing would appear when it

An explosive device was discovered on the floor of a San Diego synagogue on Thursday, San Diego police announced.

Officials found what appeared to be a pipe bomb on the floor of the Chabad of Poway Synagogue in San Diego. The device was addressed to Sen. Bernie Sanders.

The suspect, James T. Hodgkinson, of Belleville, Illinois, died from gunshot wounds to the chest after a shootout with police early Wednesday morning, according to the Washington Post. Hodgkinson had a history of mental illness.

Police found the package, which was addressed to “Bernie Sanders,” after Hodgkinson fired rounds from his rifle on a state lawmaker, who was not seriously injured.

Hodgkinson’s social media accounts show him to be a fervent supporter of Sanders and an outspoken critic of President Donald Trump.

The FBI confirmed that a package addressed to Sanders was delivered to a facility in San Diego but said the device was not explosive and was “being taken to the FBI for further analysis.”

Some residents of the city of Poway reported receiving calls to their cellphones, according to the San Diego Union-Tribune.

San Diego Mayor Kevin Faulconer said in a tweet that city officials have been notified and “out of an abundance of caution, we are taking immediate precautions to ensure the safety of our residents and visitors.”

“San Diego is a city of tolerance and diversity that embraces all,” he tweeted. “We will not be intimidated and we will not be deterred.”

“Anyone who comes to our city and threatens our people, or our way of life, or our values, or our way of life — they should be shocked and offended by that. They should be shamed and embarrassed,” San Diego County Sheriff Bill

Conceptually simple way to construct a non-zero continuous function such that its Fourier transform is non-zero

I would like to know what is the simplest way to show that there is no non-zero continuous function $f:\mathbb{R}\to\mathbb{C}$ such that $\mathcal{F}\left(f\right)\left(t\right) eq 0$ for all $t\in\mathbb{R}$.
I would like a conceptually simple argument, since I am new to this kind of question. I know that there is a basic way to construct a function that satisfies the condition, but I am not sure if it is the simplest way.
Thanks.

A:

The answer is of course that there is no such continuous function, because the Fourier transform is not a bounded function. (Consider the function $f(x) = e^{ -1/x}$ on $\mathbb{R}^+$, which is even.) But you can actually make a sequence of bounded functions $f_n$ with $\mathcal{F}f_n ot\rightarrow 0$.
Indeed, let $M>0$, $N$ be positive integers, and \$M
