According to a report from Forbes' Clare O'Connor, Match offered 0 million for the 3-year-old startup about two months ago, but Bumble rejected the offer.
Bumble was founded by Whitney Wolfe, a cofounder of Tinder who left in 2012 and filed a sexual harassment suit against the company. Forbes points out that because Wolfe previously filed suit against not only Tinder, but and IAC as well, she would have been working for the same company she sued had Bumble accepted the buyout.
The great scientist Ernest Rutherford was the first to define the concept of “half-life,” that is, the time it takes for one half of the atoms in a given quantity of a radioactive element (such as plutonium) to decay into another element (such as uranium), or for one isotope of an element (such as carbon-14) to decay into another isotope of that same element (such as carbon-12)...

However, if this is not so, it would be expected that a given water body will look younger on the basis of a shorter-lived radioisotope and that the ''true age'' would be even greater than that obtained on the basis of the longer-lived isotope.
Current research into further uses of silicon-32 include oceanic circulation, atmospheric circulation (specifically, 100-1000 year time scale exchange processes between stratosphere and troposphere), and determining ground water infiltration rates.
Si dating yields mean sedimentation rates of 0.7 ± 0.2 cm/yr for 50 to several hundred years BP and 3.1 ± 0.8 cm/yr for the past 50 years.
Water in rain, oceans, lakes, streams and glacial ice pick up these tracers through contact with the atmosphere.
The concentration of the tracers in the groundwater depends on the atmospheric concentration at the time of contact when the water fell as rain or snow, and the time since the last contact of the water with the atmosphere.
