2.2 Using the equals sign

As mentioned previously, one of the most misused mathematical symbols is the equals sign, =. It stands for the verb ‘equals’ or the phrase ‘is equal to’ or ‘which equals’, and so it should only come between two things that are equal.

3.7 Hair cell tuning

We have determined that the location of the peak of the travelling wave on the basilar membrane is determined by the frequency of the originating sound. The hair cells run the length of the basilar membrane. When a certain frequency sound stimulates a point on the membrane, it responds by moving, and the hair cells at that site are stimulated by the shearing force that this movement creates (Author(s): The Open University

3.4 Integration of anatomical features and biochemical and physiological strategies in endurers

The endurers, large animals with a relatively low surface area: volume ratio, have problems in losing heat from the body when exposed to high T a. Certain large lizard species behave like endurers, but they are evaders and evaporators too, a salutary reminder that we should not apply classification criteria too rigidly.

Droplet lens technology opens microscopy to the masses
An Australian National University scientist has discovered a simple, cheap way of turning a smart phone into a high-resolution microscope, opening the door to a revolution in science and medicine in developing countries. The transformation is made by attaching a tiny lens made of a clear pliable polymer onto the camera lens of a phone, explains inventor Dr Steve Lee, from the Department of Biomedical Engineering.

Observe Water in Winter and Summer
On Earth, water can regularly be found in three different phases — liquid, solid, and gas — each of which has noticeably different properties. For example, a boat can glide through liquid water in summer, but it cannot do so when the water turns to solid ice in winter. Atmospheric conditions, specifically seasonal temperatures, can influence the phase in which water exists at a given time. This short video segment depicts water in different seasons at the same location.  No narration.  Run
