100! has 24 zeroes. To arrive at the answer consider this: every zero is actually just a factor of 10 in the number. Every 10 is just 2*5. Also, notice that we'll have way more 2's than 5's so we only need to count the number of 5's. First, there's 20 5s in the factorization as 100/5=20 (0,5,10,15...,100). But notice this isn't all as there are numbers that can have more than 1 power of 5's in them. e.g 25. To count all numbers that have 2 powers of 5's we count the number of factors of 25. 100/25=4. Also, notice we'll only have to add a single 5 for all of these numbers as the other 5 was already counted in the single 5 multiple counting. Finally, we know this is all of the 5's as the next power of 5: 125 is bigger than 100 itself. So, 100 has 24 zeroes
Sehr gerne :) viele in Deutschland wissen nichts von diesen Praktika. Natürlich, dies ist ein sehr extremes Beispiel und auch wirklich eine Ausnahmesituation. Aber, wie auch Niklas in seinem Video erklärt, werden Praktika in vielen Ländern viel viel besser bezahlt also in Deutschland. Es kommt noch ein Zweites Video über D. E. Shaw & Co., also stay tuned :)
@@SamuelBoschMIT Das ist wirklich wahr. Da sind die Unterschiede zu den Verhältnissen hier in Deutschland deutlich. Was wohl die Gründe hierfür sein mögen. Jedoch umso besser, dass man durch Leute wie dich so tolle Einblicke erhält. Bin gespannt auf kommende Videos :)
Samuel, you are such an interesting person. I love your perspective and internship video. I think I am a little too old to follow in your footsteps, but I will suggest this video to my son.
That's a great idea, and going to happen already next weekend. I will be talking to my friend Emily, who did a quant internship for D. E. Shaw, and we will go through the differences and our experiences :)
Hey Samuel, thank you for posting this informative video. I was wondering what your resume looked like when you applied for D.E Shaw & Co. I currently go to a non-target university studying accounting and information systems.
Hey Samuel, I am currently switching my career from web development to quantitative development, but I am struggling to know where to start with modelling that you've mentioned in the video. Is it done in Excel, using C++, or through other means? Any resources (TH-cam videos, online courses, books) are appreciated.
Okay, auf die Nullen am Ende bin ich auch gekommen aber ob davor noch welche sind: Keine Ahnung. :) Meine Überlegungen waren dank mangelnder Kenntnisse in Zahlentheorie relativ pragmatisch. Zwei Nullen entstehen durch die Multiplikation mit 100 und jeweils je zwei weitere Nullen durch ((20x5)x(4x25)x(2x50)) und eine durch das x10 = 9 Nullen. Von den weiteren Zahlen sind (30,40,60,70,80,90) jeweils durch 10 teilbar d.h. min. 6 weitere Nullen d.h. 15 Nullen. 8 weitere Zahlen sind durch 5 teilbar und da es min. genauso viele Zahlen gibt, die durch zwei teilbar sind, kann man sie in *5 und *2 Terme abspalten d.h. ergo x10 d.h. weitere 8 Nullen = 23 Nullen. Eine der Zahlen (75) ist enthält sogar 5^2 d.h. eine weitere Abspaltung ist möglich = 24 Nullen.
Thanks a lot for this interesting video! I really appreciate that you've given more background information on the salary in the video description. Seems like trading is still a world of its own - although those 'tech' - hedge funds seem much more progressive (and imho more interesting) than the traditional ones. Has a career in Quantum-ML research always been your first goal or did you also consider other options (outside of academics, or maybe another area of research?)
Thanks for the nice comment Flo. Yes, I try to be really transparent about everything. I know that, for example, in Germany people don't like to talk about salaries. But I think it's important to be open about such things. Indeed, since the late 80-ties, tech-hedge-funds have been really taking over, and what they do is just waaayyy more interesting than traditional investment banking and hedge funds. I got really interested in quantum computing a couple of years ago. I am still very excited about this field, although I realized that I am not a 100% "sciency" person, as I believed before. I am super enthusiastic about startups, and I wanna make this a main focus of this channel. But I do also like to mix in trips and tricks and experiences form my past, as this is surely useful for people. Nobody starts a startup up with absolutely no experience or knowledge in any field, so I wanna help everyone accomplish exactly that :)
Thank you! Honestly, I learned this just from Wikipedia and Investopedia. It's not really rocket science, so all you've gotta do is understand how it works, and how it is different from the normal distribution. It is a bit more complicated that the normal distribution as the mean and median don't match. For example, more than 50% of all people are below-average intelligent. Sounds like a contradiction, but it is actually true as the IQ distribution is close to a log-normal distribution (because IQ cannot be negative), so the mean (or average) is not the same as the 50%-tile (which is the median). What I would really recommend you to do is to run some Monte-Carlo simulations with the log normal distribution. It's basically a long for-loop, taking random drawings from the log normal distribution. This is how most financial simulations are done. Investopedia has simple explanation for all of the finance stuff: www.investopedia.com/articles/07/montecarlo.asp But in the end of the day, doing a lot of practice with probability problems is the most important part. Once you understand these basic concepts, you will also not struggle running small simulations. I hope this helps :) You're welcome to join my live stream next Sunday, and ask me more questions :)
@@SamuelBoschMIT Omg you actually replied thank you. I am a first year mechanical engr student and I’m looking to get my masters and probably MBA in the US immediately after my graduation. I want to start preparing now and hopefully after 5-6 years I’ll get into MIT or Harvard for masters in engr,and you’ve been really helpful thank you
Hmmmm I could make a video on mathematical logic or something like that. I’ll have to think about it for a while, to see if I have enough useful ideas for a video :)
Danke 🙂 Aus Sicherheitsgründen - die haben viele super profitable trading Algorithmen die wirklich viel Geld einbringen, doch mit einem copy-past ganz einfach gestohlen werden könnten. Daher kann ich es eigentlich verstehen. Besonders wenn jemand aus einem eher unbekannten Land wie Kroatien eingestellt wird :)
Great questions! I know Niklas already made a video about CVs, so I definitely recommend checking this out because it is great. Nevertheless, as someone who hired many people for my own startup, I will also make a video at some point about CVs and interviews
Very interesting video and channel! As a Masters student in finance (and hopefully PhD student soon), I would be interested to what degree knowledge of high level finance concepts, such as asset pricing models, was required.
Thank you for the nice comment. I really appreciate it 🙂 In my case, my knowledge about finance was precisely zero. Their idea is that they get people who are good with numbers and simulations (remember, math is the same regardless of the field you work in), and then they spent the summer teaching me everything I needed to know about finance itself. It was mostly just terminology. But in your case, you would probably aim directly at a higher position, so knowing more about finance is definitely a very very good basis. Especially if you already know that that's what you want to do, studying finance is the most direct path to a successful career in the field itself.
@@SamuelBoschMIT Super interesting to know. I suppose that is also due to the technical nature of your task (derivatives pricing). Looking forward to the livestream next week.
15k pro Monat und einen kompletten background check für jemanden, der eigentlich gar nicht dort arbeiten will und sich nur "just for fun" beworben hat. Die müssen wirklich verzweifelt auf der Suche nach guten Leuten sein.
Awesome, concise and practical video;curious about Kenya as a referral point; here the political system rarely,if ever,innovate anything.The politicians merely steal and the donate to the public, churches etc! Poverty, corruption endemic...

do you mean the miscalculation was because lognormal was too unrealistic?
Man! U got a point!🤝🏻
Super Video :) 100! sollte 24 Nullen am Ende haben, weil 24 mal die 5 fünf (und mehr als 24 mal die 2) in der Primfaktorzerlegung vorkommt, oder?

I would like to work in the same position, can you help me getting the Internship?
I would be curious how much time you had for these different questions? For example for the question of how many 0s are in "100!"?
It’s in an interview so you kinda have to do it live and talk your thoughts process out loud as you do it
Can you make a video on how you study for math? Some tips and tricks etc to make maths more interesting.
Hmmmm I could make a video on mathematical logic or something like that. I’ll have to think about it for a while, to see if I have enough useful ideas for a video :)

2:45 do you mean zeros at the end of the number or zeros total? I could only solve the amount at the end :/
Yes, at the end of the number- good point 🙂
Sorry, but how would you do that?
I would like to work in the same position, can you help me getting the Internship by referring and mentoring me?
How did you CV looked like? I would realy apreciate If you can share any info on that
It's on linkedin
24 for the question
These are just the leading zeroes??
Shouldn't the total zeros be 30?
Do they really ask for your SAT scores? Did they ask you for the SAT scores?

6 zeroes
21
How did you get this number? 🙂
11 for tens
Then 2*5 ten time
