Weekly Photo Challenge : Delta

Oh, how those formulae rush back to mind!

Velocity is change of distance divided by the time elapsed, represented as

v=Δd/Δt

Acceleration is change of velocity over time, represented as

a=Δv/Δt

Delta (Δ) is not the only Greek letter used in Mathematics and Physics, but it makes its presence felt many times during our school and university years.

The express train accelerates to speeds up to 200km/hr, and then it decelerates smoothly to stop at the right point of the platform.

Weekly Photo Challenge : Focus

Sometimes it is interesting to practice using the ‘point and shoot’ camera in macro mode. The test is to get the desired subject in focus! There is no better place to try this than in gardens, and in contrasting seasons.

Spring at the beautiful Sheffield Park Gardens near Haywards Heath, East Sussex.

Of course, a this scientist interprets ‘focus’ literally; but he is very happy with the ‘blur’ achieved.

Weekly Photo Challenge : Blur (II)

I couldn’t resist offering a second entry in this challenge, when I thought about photos that might not otherwise be shared. Both offer natural blur caused by movement. In one, a man walks into view as an attempt is made to take a snapshot through the open door of a train. In the second, the movement is as a train is departing the station.
