On the 25th January, the US Press Secretary announced that in their bid to stop ‘fraud’ and waste DOGE had cancelled $50 million worth of condoms being sent to Gaza by the United States Agency for International Development (aka USAID). President Trump later repeated this claim, adding on that Hamas were using said condoms to make bombs to fire at Israel. On the 7th of February the USAID website was taken down. We fact check this claim and find out how much of the US budget was spent on USAID

In this episode, we explore hash tables, a data structure designed for efficient insertion, deletion, and searching of data using keys. The document contrasts direct addressing with hashing, highlighting the space efficiency of hash tables when dealing with large key universes. It discusses collision resolution techniques like chaining and open addressing, exploring the trade-offs between them. Different hashing methods, including division and multiplication, are analyzed for their suitability in

In this episode of Tier 1 Interventions, Jonily Zupancic continues the conversation on Three Math Rules That Never Expire, focusing on Rule #2: Subtraction is Distance. Many students struggle with subtraction when taught only as "taking away." But what if we reframed it as measuring distance? Jonily explains how this approach builds number sense from preschool through high school, making subtraction intuitive and transferable across math concepts, including negative numbers, decimals, and

Today, we are exploring suffix trees, a data structure used for solving string problems.We begin with basic definitions related to strings and alphabets, then introduces suffix trees as compressed tries containing all suffixes of a given text. Applications include substring searching, finding repeated substrings, and data compression. The discussion covers the construction of suffix trees using tries and compressed suffix trees, along with the properties that define them, modifications needed for

In this episode, we move beyond the classical and frequentist definitions of probability to explore the propensity interpretation.We examine how Peirce and Popper viewed probability as an objective tendency of random phenomena.While this approach offers an interesting perspective, and it can be useful in fields like quantum mechanics, it also raises challenges, especially when dealing with single events. We also discuss historical bias and its impact on risk management and financial

Babies born in the US to Black Hispanic or African American mothers are more likely to die than any other ethnic group in America. That is a fact. But the reason why this happens is unclear. In 2020 a study came out that claimed that black babies attended by white doctors after birth were twice as likely to die than white babies attended by white doctors. People jumped to the conclusion that the race of the doctor was leading to the different outcomes. But when you delve into the numbers, a very

We discuss disjoint sets, also known as union-find data structures. Disjoint sets maintain collections of elements partitioned into non-overlapping sets, each with a representative element. Key operations include Make-Set (creating a new set), Find-Set (locating a set's representative), and Union (merging two sets). Different representations are explored, such as arrays, linked lists, and inverted trees, along with their associated time complexities. Heuristics like weighted union and union by rank

Jump in and discover the B-tree data structure, a fundamental tool for processing queries on one-dimensional data stored on disk. We explain how B-trees efficiently support range reporting, successor/predecessor searches, insertion, and deletion operations.

DeepSeek R1 has taken the world by storm, causing a stock market crash and prompting further calls for export controls within the US. Since this story is still very much in development, with follow-up investigations and calls for governance being released almost daily, we thought it best to hold of for a little while longer to be able to tell the whole story. Nonetheless, it's a big story, so we provide a brief overview of all that's out there so far.(00:00) - Recording date(00:04) -

In this episode, we delve deeper into the frequentist definition of probability, showing how probabilities emerge from limiting relative frequencies. We discuss why this approach can be useful for mass random phenomena but falls short for single or rare events—especially in risk management contexts involving heavy-tailed risks. Through examples, we highlight the dangers of relying solely on historical data and underscore the need for more robust tools to capture the true nature of randomness.Become

Are vouchers the answer to getting services for dyscalculia? Not necessarily. How can parents find the right services for their children, or themselves? Dr. Wall gives you specific questions to ask in this episode. Learn more at www.educalclearning.com or www.thedtri.org.

El artículo presenta una introducción a la metodología de aprendizaje profundo geométrico, que busca sistematizar este campo aplicando los principios del Programa de Erlangen de Felix Klein. El objetivo es derivar los diferentes sesgos inductivos y arquitecturas de red a partir de los principios de simetría e invariancia. Se centra en una clase grande de redes neuronales diseñadas para el análisis de conjuntos no estructurados, cuadrículas,

Google claim their latest quantum computer chip is able to process something in five minutes it would take a normal computer 10 septillion years to figure out.As this is a massive amount longer than the entire history of the known universe, that seems to suggest the chip is extremely powerful. But when you understand what’s going on, the claim doesn’t seem quite so impressive. Dr Peter Leek, a quantum computer scientist from Oxford University, explains the key context.

Welcome to the fifth episode of The Logic of Risk. After introducing the classical definition, we begin a review of the main schools of thought in probability. We’ll see that some are objectivist and others are subjectivist, plus a few that position themselves somewhere in between. Among the objectivist schools, we’ll introduce the most commonly used (and abused) one: the frequentist school.Are you ready to take the risk?Become a supporter of this podcast:
