1.2.1 Influences on how we perceive diagrams A few people find diagrams unhelpful; but many people who regularly use words find the discipline of conveying ideas in diagrammatic form both sharpens their understanding of the ideas and opens their eyes to alternative views.

Diagrams can also suggest new and unexpected relationships between ideas about a si
Learning outcomes After reading this unit you should be able to: appreciate diagrams as a powerful aid to thinking and acting; distinguish between systems diagrams and diagrams helpful in systems work; demonstrate sufficient skills to ‘read’ and ‘draw’ a wide range of diagrams, following given conventions, that help improve your understanding of a situation; select diagrams suited to the needs of the situation you are investigating an
Introduction Pictures speak louder than words. But how can you use diagrams to help you? This unit looks at how diagrams can be used to represent information and ideas about complex situations. You will learn how to read, draw and present diagrams to help illustrate how ideas or processes are connected.
This unit is from our archive and is an adapted extract from Systems thinking and practice: diagramming (T552) which is no longer taught by The Open University. If you want to study formally with us

T cell signaling goes with the flow
By: JCB Activated T cell receptors stimulate actin polymerization at the periphery of the immunological synapses that form between lymphocytes and antigen-presenting cells. Babich et al. reveal that the retrograde flow of actin, largely driven by continuous polymerization, is required to sustain downstream signaling events and T cell activation. This biosights episode presents the paper by Babich et al. from the June 11, 2012 issue of The Journal of Cell Biology and includes an interview with se
Science Nation - Signing Made Easy
By: nsf From video games to cell phone apps, making sign language easier to learn
Put on the gloves. Turn on the camera and...action!
Nine-year-old Thomas Nelson is playing a video game called "CopyCat," which is a unique and fun way to learn sign language. Thomas was 2 years old when doctors determined he was profoundly deaf. His mother, Cheryl Nelson, says he couldn't hear the sound of a honking horn from an oncoming truck.

Science Nation - Surgical Robotics
By: nsf Robots help surgeons transcend human limits
At times, it's tough going for Whitney Hatchett.
"I was born with three heart defects. Two were operated on when I was 11 days old," she tells us.
That was the first of many surgeries for the 34-year-old. But none was quite like last year's. "It was either to use the robot and have three small scars on my back or if it was done conventionally, I would have a scar all the way around," she explains.

By: nsf Life erupts once again from the once lifeless mountain.
When Mount St. Helens blew its top in 1980, it wasn't a surprise that it happened, but even today the extent of the damage is hard to fathom. The eruption knocked down 100-foot trees like matchsticks and killed just about everything in its path. There have been several smaller eruptions since then, but nothing like what happened in 1980.
