<p>I posted this before but, this time I will give more hints. </p>
<p>Identify the following
J.W. & BH
HB came before BH
M.F, M.M., D.R., A.O., C.S., and R.C.are all women scientists/mathematicians.
BH is a large thing. All the others are people’s initials.</p>
<p>hint: BH stands for blackhole
hint: John Wheeler stands for JW</p>
