Vector Definition in Science

Vector Definition in Science The term vector has different definitions in science, primarily depending whether the topic is math/physical science or medicine/biology. Vector Definition in Math and Physics In physical science and engineering, a vector is a geometric object which has both magnitude or length and direction. A vector is commonly represented by a line segment in a specific direction, indicated by an arrow. Vectors are typically used to describe physical quantities which have a directional quality in addition to a quantity that could be described by a single number with a unit. Also Known As: Euclidean vector, spatial vector, geometric vector, mathematical vector Examples: Velocity and force are vector quantities. In contrast, speed and distance are scalar quantities, which have magnitude but not direction. Vector Definition in Biology and Medicine In the biological sciences, the term vector refers to an organism that transmits a disease, parasite, or genetic information from one species to another. Examples: Mosquitoes are a vector of malaria. A virus may be used as a vector to insert genes into a bacterial cell.

Why Planning Less Will Boost Productivity

Why Planning Less Will Boost Productivity It might be  a tricky thing to do in our world of overloaded, double-stuffed, triple-stacked offerings, but according to David Caolo at Unclutterer.com, the best way to give yourself some breathing room and actually boost your productivity is to plan to get less done. That’s right- under-schedule, and you’ll likely over-deliver. Having recently found myself in a 3 month stretch of hyper-scheduled workload-excess, I can relate. If I plan to get two things done a day, I can accomplish them and add on a bonus ask. If I have to get through 4 things before I can go to bed, anything that distracts me or comes up more urgently may derail my whole day.Start by planning the night before- ask yourself, â€Å"What should I work on first?† as you get ready for bed, so by the time you’re back at your desk, you’re ready to go.Even better, Caolo suggests not scheduling anything for the last hour of your day. This leaves you free to handle things that come up, it lets you tie up projects that are taking too much time, and allows you to sort through email and last-minute requests for the next day. I love to send a recap email or handle all my administrative tasks at the end of the day. It’s soothing- and frees up my first hour for urgent things instead of the slow, sometimes tedious wind up.See what happens if you pull the plug on the auto-scheduler and under-do it for a change- you may be surprised how much you can get done!Build a Time Buffer Into Your Schedule
