Class highlight: Mr. Chukwujekwu Anah showed a Fantasy Premier League points model. I’ve built a football prediction model of my own, so it gave me a clear picture of what to aim for.
Thanks to him and @TechSphereAcad for a great start. On to Day 3 📊

What clicked: broadcasting. NumPy wouldn’t multiply 20 prices by a 20 × 7 table until I reshaped the prices into a column. Reading the shape error told me exactly what to fix.

Day 1/30 of learning data science in public 💻
Built a 30-student grade book in NumPy, no loops over the data. Biggest lesson: curved = scores doesn’t copy the array, so edits hit both.https://t.co/7zsgE84nC7

Today was the kickstart session for TechSphere Academy’s Aurora Cohort, and honestly, it felt different from the usual webinars.
They had their own vibe, and Aurora, meaning new beginnings, really resonated with me as someone transitioning from HR into tech.
One of the biggest differences between the Harry Potter books and the movies is how Harry deals with the Elder Wand. In the books, his decision is far more thoughtful, strategic, and meaningful. He doesn’t snap it in half or destroy it, and that changes the entire meaning of the ending.
In Harry Potter and the Deathly Hallows, after defeating Lord Voldemort, Harry doesn’t break the Elder Wand in two as he does in the movie. Instead, he returns to the headmaster’s office and speaks to Albus Dumbledore’s portrait. There, he fully understands how the wand’s allegiance works and why it belongs to him,not because he killed anyone, but because he disarmed Draco Malfoy.
Then comes a crucial moment the movie leaves out: Harry uses the Elder Wand to repair his own holly and phoenix feather wand, which had been damaged. This is deeply symbolic. Harry doesn’t want the most powerful wand in the world; he wants his own wand back. He wants to return to his normal life rather than hold on to absolute power.
After repairing his wand, Harry reveals his plan to return the Elder Wand to Dumbledore’s tomb. His reasoning is simple: if he dies undefeated, the wand’s power will eventually die with him. He doesn’t need to destroy it physically; he believes he can end its dangerous legacy by ensuring that its power is never passed on to another wizard.
The difference is significant. The movie gives us a quick, dramatic gesture, while the book gives us a decision rooted in reflection, responsibility, and an understanding of the wand’s history. Harry doesn’t simply discard the Elder Wand; he chooses not to pursue its power.
Harry never wanted the Elder Wand in the first place. He just wanted his old life back, and that’s what makes the book ending so much better.
