The real meaning of “Cassandra”
It turns out that “Cassandra” is the female form of “Cassander”, one of the four generals who split up Alexander the Great’s kingdom after the ruler’s death.
“Cassander” means “light of man”. No wonder my mum’s admonitions to me NEVER TO BE FAMOUS didn’t work. This Bible verse speaks to me personally: “Ye are the light of the world. A city that is set on an hill cannot be hid” — Matthew 5:14 (KJV). In other words, I cannot be hidden. It’s also no coincidence that I’m born at a time when anyone with tech savvy and grit can dig up information about us. Nobody is hidden anymore, not even Luddites. Everyone is out there to discover everyone else’s secrets.
Therefore, the next time you read that the meaning of “Cassandra” is unknown, you’re looking at an untruth. Lamentably, in this age of female empowerment, almost everyone has taken for granted that “Cassandra” is a girl’s name and never considered that, historically, some girls’ names were derived from boys’. I can think of Victor/Victoria, Eric/Erica and Julius/Julia. Your examples may be better than mine.
Heads-up for skimmers or superficial readers, because you’ll need to read this paragraph many times lest you take my words out of context. This sorry revelation easily suggests a claim, which I duly hope is erroneous, stating “females don’t matter without males”, which, as we can see from recent history, has been challenged time and time again. On the flip side, how many men’s names are derived from women’s, how many names are unisex, and, most importantly, is gender supposed to be a point of contention and division, or a reason for unity, community, cooperation, mutual “put down your weapons” vulnerability, and, above all, love?
I stumbled across “Cassander” as I was studying Daniel 8’s prophecies today, and I wondered about its fulfillment in history, since verses 8 and 22 mention the split of a great power into four, and that reminded me of Alexander the Great. Thankfully, it’s rare for a man to be called “Cassander” now, lest someone mishear and disrespect him.
This is why #girlsinstem matter
The standard workout music accompanying my HIIT exercise videos has the disadvantage of aggravating inappropriate emotions in me (the lyrics having something to do with falling in love and hearts beating in time and being young and wild and free, and such sentiments had caused me more trouble than I could handle).
Fed up with it, last night, I finally wrote my own bash script so that I can listen to podcasts while keeping fit. This is why it matters that we have #GirlsInSTEM #WomenInSTEM #GirlsInTech #womenintech #GirlsWhoCode #WomenWhoCode!!!

Carnival of Mathematics #172
You’re visiting Carnival of Mathematics #172 hosted by Cassandra Lee. Find all Carnivals here and the previous Carnival (#171) here. Many thanks to the Aperiodical for the wonderful opportunity to host this Carnival.
The Roman representation of the number 172 comprises the initials of my English name, the chromosomes determining my gender and the eating utensils that I use daily. Yes, that’s CLXXII. *gasps at the sudden weight on her shoulders*
Without further ado, let’s begin with something light-hearted. It’s easy to show that 172 = 2 × 2 × 43, an even composite number; it doesn’t appear special until you also learn that 172 is also a deficient number (the sum of the factors is less than the number itself: 2 + 2 + 43 = 47 < 172) and an evil number (!), which means it has an even number of 1’s in its binary representation (17210 = 101011002). Note that, if the units digit is relabelled the “zeroth/0-th” digit, then you can verify that the binary representation of 172 (= 101011002) has the following property:
The n-th digit is 1 if and only if n is prime.
Furthermore, 172 is in the lazy caterer’s sequence at n = 18; the maximum number of pieces you can get with 18 cuts of a circular pie is 172.

Who Am I to Call Myself a Writer?

I wonder how many of us are suffering because we didn’t write to encourage, caution or entertain.
I am writing to the high school and college students who dream of publishing their first novel, yet cringe at the idea of prematurely calling themselves “writers”.
