Did you solve it? Logical philosophers | Logic puzzles

Earlier today I set you the following three puzzles.

1. Late Wittgenstein

Wittgenstein has been murdered. The culprit is one of either Friedrich Nietzsche, Lou Andreas-Salomé, Karl Marx or Ludwig Feuerbach. They make the following statements. You have been correctly informed that guilty person always lies, and everyone else tells the truth.

Nietzsche: Salomé is the culprit.
Salomé: Marx is innocent.
Feuerbach: Salomé’s statement is true.
Marx: Nietzsche’s statement is false.

Who killed Wittgenstein?

Solution: Nietzsche.

If Nietzsche is telling the truth, then Salomé is the culprit and therefore a liar. Thus Marx is not innocent, meaning he is the culprit. We can’t have two culprits, since this is forbidden in the setting of the question, and so we are led to contradiction. Nietzsche must therefore be lying. If he is lying, then everyone else tells the truth, which they can without contradiction. Thus Nietzsche killed

Games Like ‘Fortnite’ and ‘Minecraft’ Helped Some Kids Survive Pandemic Boredom. Could They Also Help Counter STEM Learning Loss?

Sticky problems abound in education these days, but one recent afternoon as teacher Nathan Finley walked students through the latest level of a new, original maze-like video game they were designing, a particular problem loomed large.

Finley couldn’t get the level to end.

“We just now created our ‘end object,’” he narrated over Zoom to the class, explaining that if a player’s avatar, working its way through the maze, collides with this invisible digital item, it should prompt the computer to display a “You Win” message, end the level, and send the player on to the next one.

“So far, it still isn’t working,” Finley said cheerfully, alternately checking lines of code and clicking on objects populating the screen. Perhaps it was the code they’d written together, or something else. “So we need to figure out what’s going on here.”

LastPass Identifies Risks, Solutions, and Strategies for

BOSTON, Aug. 25, 2021 (GLOBE NEWSWIRE) — LastPass by LogMeIn, an industry leading password management solution, released today a study on the solutions and strategies needed to protect critical systems and sensitive data based on an IDG survey of 300 IT professionals employed at higher education institutions. The company’s report suggests the best strategy to stop cyberattacks in higher education is instituting better password hygiene through a password management tool.

The IDG survey found that 88 percent of institutions suffered an IT security infringement because of poor password management this year alone. Four in 10 respondents reported difficulty keeping up with cyberattacks, and 32 percent were stymied by the task of protecting every entry point and device accessing the institution’s data and applications.

A password manager can help solve these problems. Password management involves storing, securing, and managing credentials by following best practices including saving passwords in an encrypted, digital
