Christmas is nearly here, and Santa’s legendary overnight delivery service is about to spring into action.
But how does one jolly man and a sleigh defy physics to deliver billions of gifts?
Let’s dive into the data.🧵
#SantaScience #ChristmasMagic #ReindeerPower #GiftDelivery
25/ Wrapping it All Up 🎁🧵
This #Christmas, let’s remember #Santa is more than just a story:
Santa is a…
#Tradition
#Face
Maybe even a #Science⁉️🧬🤷♂️
Thanks for reading about our exploration of Santa’s Facial Phenotype!

24/ #SantaScience🤝🎅
📄Passion project fuelled by festive curiosity #NextGenPhenotyping & #MachineLearning
🚨Evidence #Santa *must be* real✨
🙌Thanks to friends/family/colleagues for support & encouragement @mft_iMRare @MFTnhs @FBMH_UoM @ManchesterBRC @HullYorkMed @UniOfYork
23/ Study Participants🙌🎅
Our research wouldn’t be possible without the generous participation 👏 from individuals presenting @Google Images as
#Santa
#AdultMen
#ElderlyBeardedMen
#ElvisPresley
#ElvisPresleyImpersonators
👇#OpenFace composite facial averages

22/ Santa in the BMJ!🎅🗞️
@bmj_latest🎄Xmas News covered our research; thanks @drshaungriffin for spotlighting 🙌
#SantaClaus Face research establishes evidence🎅=real & recognisable person!✨
(…other explanations possible🤔🥸🤷♂️)

21/ #StNic Facial Paradox👤🧩
🤖🖥️#SVM analysis identified:
👴StNic Face= ElderlyBeardedMan!
🦌Walter Shields= AdultMan! (❌🎅)
Could this reflect:
🤔Divergence in portrayal due to iterative promulgation & uniform depiction, shaped by culture & tradition?🎅

20/ Santa’s Face is Distinctive🎅

💁🏼♂️Santa mingles with EBM
✨2 discrete Santa Face clusters on #tSNE
🎩🎯SVM identified Santa with mod-high specificity🔥
#SantaScience
18/ Santa Faces Model Validation 🎅🧐
We validated our approach by demonstrating our #SVM could distinguish faces of
#ElvisPresley vs #ElvisPresleyImpersonators🕺
Accuracy 0.81 | Precision 0.81 | Recall 0.87
📊AUC 0.94 (p< 0.001)

17/ Santa Faces Sorting🎅🧐
Support Vector Machines (#SVM) were trained to recognise Face Vectors for each group📊
🔸70% Training : 30% Testing
🔸Grid search cross-validation
Our SVM worked like @harrypotter #SortingHat (for Faces!)🎩✨

15/ Hypothesis testing: Santa’s face is distinctive🎅
First, we compiled our study groups= individuals fulfilling eligibility criteria presenting on @Google images as
1️⃣ #Santa
2️⃣ #AdultMen
3️⃣ #ElderlyBeardedMen
4️⃣ #ElvisPresley
5️⃣ #ElvisPresleyImpersonators

11/ Historical Phenotyping of Santa🎅
🗞️ 1823 report in🗽Troy Sentinel
🔍Earliest attempt to #phenotype Santa’s face?
As an exemplar of data harmonisation (#CDM) we mapped 200-year-old facial descriptors to The Human Phenotype Ontology (#HPO) @hp_ontology🧬🤓
#SantaScience
10/ Is Santa an owl?🎅🦉
Research @uni_tue found Santa’s behavioural #phenotype aligns with evening #owl (night chronotype)
Statistically sig. results (binomial test, p=0.013)
👉Study @tandfonline https://t.co/UqpTgZFTBX #SantaScience
📸 = 🎅+🦉is Santa’s #Face distinctive⁉️
7/ Toddlers can authenticate Santa🎅
🇦🇺Children as young as 3 in an Australian study said they could authenticate #Santa
🗣️Based on appearance🎅✅

🤔…Could this ability rely on Santa's instantly recognisable #Face?

Bouncing into the holiday, with America's Mr. Science, engineering bouncy balls, in Santa's Science Toy Workshop, at Union Local Elementary School, in Ohio. #Science #Toy #Ohio #HookedOnScience #MrScience #SantaScience #Science
🎙️Unwrapping the holiday magic with Ask Dr. Chance! Next up: we're diving into the enchanting world of Jolly Saint Nick and the Science of Santa Claus!
Drop your festive queries below, and let the holiday science sleigh ride begin! 🚀🎁 #AskDrChance #SantaScience 🎙️
@EddieDexter @neiltyson I think it's more likely they're taking the energy of the quantum vacuum, but I'm not sure.
There's so many unanswered questions in #SantaScience
@rad_shiba @neiltyson Assuming General Relativity is right, we live in a block universe. Shattering space-time means the whole block gets broken, from the Big Bang to the infinite future. As this hasn't happened, it is proof that nobody has done the observation you specify. #SantaScience
