What will happen when a ringing tuning fork is lowered into water? When struck, the double-pronged metal rod vibrates at a constant frequency — and thus emits a constant pitch. The naked eye can’t spot the vibrations, but dipping the tuning fork in water and slowing down the footage make them anything but invisible. What […]
WHAT IS units in chemistry?
WHAT IS units in chemistry? Chemistry primarily uses five of the base units: the mole for amount, the kilogram for mass, the meter for length, the second for time, and the kelvin for temperature. The degree Celsius (oC) is also commonly used for temperature. What is the formula to convert kg to lbs? 1 Kilogram […]
Why are unit tests useless?
Why are unit tests useless? Unit tests ossify the internal structure of the code. All the unit tests are suddenly rendered useless. Some test code may be reused but all in all the entire test suite has to be rewritten. This means that unit tests increase maintenance liabilities because they are less resilient against code […]

What does listening to 528 Hz do?
What does listening to 528 Hz do? According to the current study, sound waves with 528 Hz frequency in 100 dB intensity induce testosterone production in brain by enhancing StAR and SF-1 and reducing P450 aromatase gene expression. Frequency of 528 Hz also reduces total concentration of reactive oxidative species in brain tissue. How many […]
