The necessary mindset to learn Blender is to have a sense of curiosity and fun. Blender, today is professional-grade software. The opening screen of Blender would be daunting. You would feel that it is highly complicated and confusing. Its user interface has many windows, hundred of buttons and options with multiple levels of dropdown menus and settings. A simple strategy to gain control in working with Blender is to enlarge your learning circle step by step gradually. Biting more than you can chew at one go doesn't work. It may quickly put you off.
Search for a way to understand and learn the particular task on hand. The first place to look for help is the web. Hundreds of tutorials and videos are there to help you find your way. As you work your way forward, pause to think and analyse where you are erring. The blind effort is meaningless. The consistent effort with focus and clarity in thought and action will speed up the learning process.
A great strategy to speed up learning Blender is to team up with like-minded individuals with whom you can share your learning and queries. Form a collaborative network. The approach should be a win-win approach.
It is important to remember that hundreds of individuals on the web are ready to share and assist you in learning. All that you need to do is seek help and knowledge.

There are several aspects that you need to know to get comfortable with working in Blender 3D.

  1. The basic layout and controls in Blender are substantially different from the general application, which we are generally familiar with. It has been designed to make working with Blender more fast and efficient from a professional's point of view. Hence the difficulty faced by a newcomer. Once we get over this hurdle, things get much more comfortable and enjoyable. Then learning Blender become fun.
  2. First, we need to get comfortable with the Blender interface - its various windows, mode of operation, the different control panels and buttons, drop-down menus and features. It will cover getting familiar and comfortable with Blender.
  3. We need to learn how to open and save Blender files, both programme files and the final image or video output. We need to know how to import photos or data into Blender.
  4. The basic idea of 2d and 3D concepts, orthographic and perspective, is essential to make good progress with Blender.
  5. The concept of basic working modes like Edit mode and Object mode should be clear and work in these modes.
  6. While Blender can be used for practically any application in the CG domain, to start with, we must decide what is that we want to develop. For example, do you want to design a table or a flower vase or a cup or robot? We need to start with simple designs and gradually move in to make more complex designs based on our skill level in using Blender.
  7. In the case of the design of any object, the broad steps are outlined below. It would significantly help full to design a product. Let us take up designing a cup to keep things simple to begin with.
    • Design the basic shape of the cup in edit mode, design the hollow part and the handle. Join them into a single part. 
    • Smoothen the surface to make it look realistic when we see it in the object mode.
    • Add a colour (material and shine- diffuse and specular ) to the object.
    • Add a plane on which the cup will be kept, set its size. Set its material.
    • Set up the camera and view-angle and position to get the desired view.
    • Add lights to illuminate the cup and the base plane.
    • Render the cup to see the final image.
    • Save your Blender file and the output files in the image or video format. Save at each stage. Save frequently.

Getting an overview of the workflow involved in any project like the one discussed above makes learning Blender easier. For any other project taken up with Blender, whether it is animation or game development, or any other project involving Blender, this sort of approach would make the whole process more organized and systematic. Plan your steps to achieve the final result. Jumping in into design, with an idea that, I will think as I make progress, may work for experimental purpose only.

While we learn using Blender, we may get many guidelines and step by step instructions to achieve our result. The instructions may sound like," Press Diffuse button and set the strength to 0.8, click on button x, select x mode, go to the panel surface and set surface to Background ...".

While we followed these instructions and got some result, we need to review the steps that we followed in this process and understand which step leads to what and play with those controls to gain familiarity. All these instruction fall under the "HOW" part of the learning process.

Moving on to the "WHY" part, we need to know why you do something to apply this learning in our next project. These thoughts may sound like high funda to a beginner, but it has its value, and we would realize it as we make progress.

One gem of an idea for an individual aspiring to learn Blender and gain expertise is the concept of "Learning to Learn". While you want to learn something, how do you learn? What is your learning process? Suggested steps for learning maybe something like the one listed below:

  1. Get to know something. Example: Render Engine - Cycles
  2. Trying to know what Render Engine is and what Cycle render is.
  3. Checking in the web, reading up some books, looking up some tutorials and videos.
  4. Getting to know different types of Render Engines in Blender. What are their functionality and applications? Which one is used for what purpose?
  5. Discussing with your friends.
  6. Identifying the settings and controls to set Render Engine to Cycles and rendering.

It all boils down to having a child-like curiosity to discover, learn and have fun all along. Whenever you feel tired, take a break.

Learning Blender should not be made into a back-breaking, tedious activity.

To work efficiently on any task, we take up, we must know how best to use the tools involved in completing the task. The more you know your tools, the better and faster is your result.

We can cite many examples to prove this point. Consider the few examples given below:

  1. Writing and editing a text matter using MS Word.
  2. Using the remote control of your TV or Audio system or a Game console.
  3. Driving your new two-wheeler.
  4. Using a new software tool.
  5. Using your new mobile phone.

The moral of the story - learn your tools well before you venture into creative work. Blender has many buttons, Dropdown menus, Windows and Panels. Spend time to get familiar with these controls. It is worth the effort.

Blender is designed to work with both hands -the left one may be used for keyboard shortcuts, and the right hand to handle the mouse and number pad buttons. Learn the keyboard shortcuts. It makes life more comfortable in the long run.

Further, you will find that there is more than one way to do it for accessing any feature or option. Please get to know them and choose the one with which you are more comfortable.

It's all 0s and 1s.

In Computer Graphics, for all the creative work you do, the result is images of static or dynamic characters with light and sound effects. Inside the computer, it is all 0s and 1s, bits and bytes.

Let us consider making a flower vase as an example to understand this viewpoint. The steps involved would be like the ones listed below:

  1. Create the surface, which would be shaped like a flower vase.
  2. Add some colour and shades to the surface.
  3. Set up some lights to illuminate the flower vase.
  4. Set up the background, if required.
  5. Set up the camera to get the desired view.
  6. Process this setting to get the final image.

In Blender, all these activities are stored as data. What you do with Blender it is data. When you change the flower vase's shape, you change the position of the vertices, edges, and nodes. You may change its size. When you add colour and shade, there is some change in data; when you add lamps, there is a change in data, and when you set a camera and its view, it is some change in data.

All the images and details related to the scene are internally stored as data. Once we understand this concept, it would be easy to see why you change various parameters and settings to get the desired result. Blender allows us to write our scripts using Python language to give us greater control and versatility in our work. These parameters can be programmed to give precise control of how a character behaves with all the related setting.

Blender is a full-featured free software package under the open GPL, run on Windows, Linux or Mac Operating system. It is a 3D development package.

The primary motivation to write this blog springs from my deep desire to share the rich features of Blender with the young at heart and empower them to explore a wide range of opportunities to build their career in the CG field while enjoying the whole learning process every single day.

It can be used for Modelling, Texturing, Rendering, Animation, Composting, Video editing and Game Development. Anyone interested in Computer Graphics can learn Blender, which offers a rich set of tools comparable to the best commercially available packages like PhotoShop, Maya, and 3D Max.

Anybody who wants to develop content for the Advertisement industry, still/animated graphics for Websites, motion graphics, 2D/3D visualization of any product or data, character and scene development can use Blender.

The development of Blender was started in 1988 by Ton Roosendaal as NeoGeo in Netherland, where it quickly grew up to become the largest animation studio. In 1995 this complete software was rewritten, which was the first version of Blender. Since then, it has undergone multiple revision and evolved to version 2.9 as of date. Blender Foundation is based in the Netherlands, which is the headquarters from where the necessary development of Blender is done and coordinated.

A vast community of users supports Blender spread worldwide, both novice and professionals and developed by the Blender Foundation and independent developers. Learning Blender at the entry-level and advanced level is supported by a range of materials available on the web. Tutorials, Blogs, websites, videos, and interact with other users in professional sharing networks like Github, Stackoverflow, Reddit facilitate the learning process. Many popular websites provide online learning courses for Blender, starting at the entry-level and covering advanced levels. A quick search on the web would yield great results and open the door to you into a world of fun, excitement, growth and prosperity.

It's undoubtedly a boon, but in some context (cancer), it has to be considered as a curse.
Replication of DNA is one of the essential and eminent processes of the central dogma of life. This occurs in both prokaryotes and eukaryotes. In prokaryotes, replication of the double-stranded DNA and termination is simple as it is a circular one. Whereas, in eukaryotes, it's a little bit complicated as it's the linear one. As the replication continues in the dividing cells, the chromosomes become shorter after each cycle.

DNA Testing: Can Telomeres Tell You About Aging and Disease Risk? | American Council on Science and Health

After a certain number of cell divisions, the cells lack further division and enters senescence under normal condition in somatic cells because the necessary codons on DNA which are involved in many protein products (transcription and translation) are gone.

So, here the focus is on how telomeres are trying to keep most of the information intact even after so many replication cycles.

Telomeres:

Specialized structures at the ends of the linear eukaryotic chromosomes consist of many tandem repeats of short oligonucleotides usually in the form of 5' (TTTTGGGG) in one strand and 3' (AAAACCCC) in the complementary strand. The structure of telomeres poses a particular problem (End replication problem). DNA replication requires a primer starting at the end nucleotide and replace it by the standard mechanism; This problem is solved by Telomerase which adds telomeres to chromosome ends after the removal of primers from leading and lagging strands of DNA.

MECHANISM:

Telomerase contains both RNA and protein components. The RNA component is 1.5 copies of CCCCAAAA oligonucleotides repeats, and this acts as an RNA template for the synthesis of TTTTGGGG strand of the telomere. Telomerase acts as a reverse transcriptase that synthesizes only a segment of DNA that is complementary to an internal RNA template. Telomere synthesis requires a short TTGG primer and proceeds in the usual 5'to 3' direction. So after synthesizing one copy of the repeats, the enzyme must be repositioned to resume extension of the telomere.

One unique feature of guanine residues is non-Watson crick G-G base paring which is required as a primer to synthesize the complementary strand.

In somatic cells, gradual shortening of telomeres with each cell division ultimately leading to the death of the cell lines as they don't have telomerase activity. In germline cells, telomere lengths are maintained by Telomerase.
So, Telomeres in human somatic cells gradually shorten as an individual age and finally leads to death. In a diseased condition like cancer, telomerase activity is seen in the cell lines, and we consider it as a curse, which causes drastic changes in the whole organism by suppressing the defence mechanisms which I will discuss in the next lesson.

Hi Priyanka, 

Projection is an anticipated data that is forecasted for a specific set of conditions. As its a predicted set of information, it is not a REAL value that is currently in place. 

Whereas when we talk about the View, it refers to the real data that is existing and reflects the same. For instance, when you are referring about a projection on a data, its dependent on the current set of data -- for example, the projected value of population after ten years can be calculated based on the past set of information/values. Whereas when we refer about a View, we would take a particular instant and fetch the exact information and data that is currently residing, which is then reflected.
