- The year is off: reliable biographies say Böger became deputy chair of the SPD parliamentary group in 1990, not 1992.
- The award date is wrong: sources show Michael Müller handed Böger the Federal Order of Merit on July 15, 2019, not in July 2020.
- The timing is wrong: the new Berlin school law took effect on February 1, 2004, not in August 2004.

- This arithmetic is off: $50 million spread over roughly a decade is about $5 million per year, not $10 million per year.

- The Technion medical faculty was established in 1969, not 1979. 1979 was the year its new building was inaugurated after Bruce and Ruth Rappaport helped fund it.
- GTIIT’s own 2020 materials do not show aerospace starting by 2020. In July 2020, the institute said it had four undergraduate majors, and aerospace was not one of them.
- This mixes up LZ and LZW. Lempel and Ziv created the earlier LZ algorithms in the 1970s, while LZW was Terry Welch’s 1984 modification.

- Anthropic has not promised to preserve model weights regardless of circumstances. Its published commitment is narrower: it covers certain models, lasts at minimum only for the lifetime of Anthropic, and explicitly allows extreme exceptions such as legal requirements to delete weights.

- Zhang et al. did not find regularization had only a tiny effect on test accuracy. They reported a large 18-point top-1 ImageNet drop when regularizers were removed, and explicitly said regularization improved CIFAR-10 generalization too.

en.wikipedia.org/wiki/Atom
- This is incorrect. Even for individual isotopes, atomic masses are not exact whole-number multiples of hydrogen’s mass; precise measurements show systematic deviations caused by nuclear binding energy.
- This is outdated under the current SI. Since the 2019 redefinition of the mole, one mole is defined by an exact Avogadro constant, so the molar mass of carbon-12 is no longer exactly 0.012 kg/mol.
- This overstates the share of Milky Way baryons locked in stars. Current sources describe a much larger gas-and-dust component, with roughly 6×10^10 solar masses in stars out of about 10^11 solar masses of baryonic matter, and a hot gas halo whose mass is comparable to the stars’ mass.
- This overstates the mass gap. The proton is about 1,836 times heavier than the electron, so the difference is a bit over 3 orders of magnitude, not 4.

- On a properly configured non-rooted Android device, another app or attacker cannot simply edit another app’s `shared_prefs` file. Android stores app-private preferences inside the app sandbox, and bypassing that isolation requires a device compromise, root, or an explicitly enabled debugging/sharing path.

en.wikipedia.org/wiki/SQL_injection
- OWASP did group SQL injection under the broader “Injection” category in 2017, but that category was ranked #1 in the 2017 Top 10, not #3.
- OWASP did not say injection was found in 94% of applications. It said 94% of applications were tested for some form of injection; the page separately lists average coverage as 47.90%.
- This example is not valid SQL comment syntax. Major SQL dialects use `--` and `/* ... */`; MySQL’s third comment style is `#`, not `{`.
- The confirmed number was far lower than 400,000. The UK ICO says the attacker accessed the personal data of 156,959 TalkTalk customers.

en.wikipedia.org/wiki/SAP
- SAP’s audited 2025 operating profit was €9.617 billion, not €10.293 billion.
- SAP’s audited 2025 total equity was €45.073 billion, not €45.240 billion.
- On April 13, 2021, SAP announced a partnership and a planned FSI unit; the name “SAP Fioneer” was announced later, on May 12, 2021.
- SAP’s audited annual financial statements are for years ended December 31, not March 31.

- The 90-day presidential certification requirement came from the U.S. Iran Nuclear Agreement Review Act, not from the JCPOA itself.
- On May 8, 2018, Eastern time was on daylight saving time, so the correct label was EDT, not EST.

en.wikipedia.org/wiki/Criticism_of_the_Iran_nuclear_deal
- U.S. officials did not classify the JCPOA as an executive agreement. The State Department said it was a nonbinding political commitment, 'not a treaty or an executive agreement.'
- That is not what Gohmert offered. He said he would not run for re-election only if congressional leaders treated the Iran deal as a treaty and held the constitutional votes he demanded.

- There are more than two academic CHIP clinics. By March 2026, other academic centers such as NYU Langone, UCSF, and Dana-Farber also publicly described dedicated CHIP programs or clinics.
- This mixes up allele fraction with cell fraction. CHIP is defined by a mutation with VAF ≥2%, which for a heterozygous mutation corresponds to about 4% of blood cells carrying the variant, not 2% of blood cells.

- U.S. cancer registry data do not show that over 90% of pancreatic cancers are metastatic at diagnosis. SEER reports about 51% are distant/metastatic at diagnosis, with another 28% regional and 15% localized.
- Clinicians have long had established ways to assess immune function. Standard immune evaluation predates organ clocks and includes tests such as immunoglobulins, lymphocyte subset counts, complement testing, and phagocytic-function assays.

en.wikipedia.org/wiki/Exit_scam
- The $4.3 billion figure was for broader crypto crime/scam losses in 2019, not exit scams alone. Contemporary reporting on the same estimates put exit-scam losses at about $3.1 billion, with the rest coming from other categories such as misappropriated funds and Ponzi schemes.

- Friendica did not become ActivityPub-compatible in 2010. Its official changelog says ActivityPub support was added in version 2018.09, released on September 23, 2018.
- Hubzilla was not ActivityPub-compatible in 2015. Hubzilla’s own timeline says ActivityPub was added later, around 2018, via the PubCrawl addon.
- Discourse had official ActivityPub support earlier than 2025. Discourse’s official ActivityPub plugin was publicly announced on May 31, 2023.

- The name "Hippopotamus" predates the 1966 Petrosian–Spassky match. It was already in use in the 1950s and appeared in J. C. Thompson's 1957 booklet *Hippopotamus Chess Opening*.
