What is mooching?
Mooching refers to aimlessly wandering around, begging or sponging off others. Due to market crises all over the world, families in the US have taken to mooching others as a means to cut costs on a daily basis. This includes bumming rides from friends more frequently than before, asking colleagues if they need their wallet when going out for lunch and not meeting the bellboy’s eyes to avoid tipping.

What is the Hadrian Wall?
Hadrian Wall was a frontier that began to be built in 122 AD by Roman Emperor Hadrian. It is located in northern Great Britain. It stretched for 120 km, was 15 feet high and 10 feet wide. It ran from Wallsend to Bowness-on-Solway in the west to the Tyne River near Newcastle in the east. It was established to prevent military raids on Roman Britain by the Pictish tribe in the north, to improve economic stability and provide peaceful conditions in Britain. It is thought that the gates of the wall would also have served as customs posts to allow trade taxation. A significant portion of the wall still exists. One of the most popular tourist attraction in northern England, it was made a UNESCO World Heritage Site in 1987.

Which is the oldest lighthouse in the world?
The first definite and documented lighthouse in the world was the Pharaohs of Alexandria built in 200 BC, although beacons were certainly used before that. The oldest working lighthouse in the world is at La Coruqa in north-west Spain near the town of Ferol. A lighthouse has been on this site since the time of the Roman emperor Trajan. The world’s first stone lighthouse tower at sea was the Smeaton Eddystone lighthouse built in 1756-9. Smeaton is today known as ‘the father of civil engineering’. When his lighthouse was finished, it was lit with just 24 candles. Today, the power of lighthouse lights can be equivalent to as many as several million candles.

How is an atom’s mass measured?
The atomic mass of a specific atom or molecule is determined by using an experimental technique called mass spectrometry. This technique separates different isotopes of atoms to allow determination of the percent abundance or isotopic composition of the element in the given sample. Each isotope of the element appears as a peak in the mass spectrum. The intensity (height) of each peak depends on the abundance of that isotope in the sample and the unique location of the peak on the x-axis indicates the mass-to-charge ratio of the isotope. Knowing the charge on the isotope, we can calculate the mass of the isotope and from the relative abundance of different isotopes of the elements, the average relative atomic mass is calculated.

What is Bowman’s Capsule?
Each human kidney contains about 1 million filtering units called nephrons. The nephron has a renal tubule and dilated blind end like a funnel. This dilated funnel like part is called Bowman’s Capsule. It has a tuft of capillaries. The fluid which comes out of these capillaries is filtered by Bowman’s Capsule. The renal tubules do further processing to make 1.5 litres of urine out of 180 litres of filtered fluid in 24 hours.
