Any semialgebraic function on [0,1] is real analytic on finitely many subintervals.
Claim:
Every semialgebraic function defined on the unit interval [0,1] is real analytic on [0,1] except possibly at finitely many points.
NOT BS
Science
Research findings, viral studies, and scientific claims under the lens.
In water, ionic color usually comes from hydrated (aqua) complexes.
Claim:
Chemists often refer to the color of an ion in aqueous solution (the ion plus its hydration shell) as "the color of the ion" for ease of communication, rather than explicitly saying "the color of the ion plus water."
HARDLY BS
Every second-countable topological space is Lindelöf in standard topology.
Claim:
If a topological space X is second countable, then every open cover of X has a countable subcover (i.e., X is Lindelöf).
NOT BS
Roman mortar’s main ingredients and formulation are well documented and reproducible.
Claim:
The formula of the mortar used in construction in the Roman Empire is still unknown.
TOTAL BS
The Jacobian conjecture remains an open, unproven problem in mathematics.
Claim:
The Jacobian conjecture is true.
TOTAL BS
In ZF set theory, some infinite Dedekind-finite sets lack countably infinite subsets.
Claim:
Every infinite set contains a countably infinite subset.
MOSTLY BS
No confirmed experiments have observed any particle exceeding light speed in vacuum.
Claim:
At least one particle can travel faster than the speed of light in a vacuum.
TOTAL BS
No confirmed scientific evidence shows extraterrestrial life exists anywhere.
Claim:
Extraterrestrial life exists somewhere in the universe.
MOSTLY BS
In metric spaces, compactness is equivalent to completeness and total boundedness.
Claim:
A metric space is compact if and only if it is complete and totally bounded.
NOT BS
UV-Vis spectroscopy is widely used for routine pharmaceutical analysis and quality control.
Claim:
Ultraviolet-visible (UV-Vis) spectroscopy is a common analytical method in pharmaceutical science.
NOT BS
Remote sensing improves crop management by detecting stress and optimizing inputs.
Claim:
Remote sensing can improve food production.
NOT BS
Microbial fuel cells can treat wastewater while generating electricity in lab and pilot systems.
Claim:
Microbial fuel cells can potentially be used to treat wastewater while generating electricity.
NOT BS
Many inorganic binary formulas list the more electropositive element first.
Claim:
When writing a chemical formula, the core rule for deciding element order is to write the more electropositive (lower electronegativity) element first and the more electronegative element last.
SOME BS
Chemical bonds are electron-density interactions, and curved bonds are a common representational convention.
Claim:
In real molecular structures, chemical bonds are not physically curved, and the curved appearance of bonds is solely an artifact of the limitations of physical ball-and-stick model kits.
MOSTLY BS
In most soils, microbes consume root-released sugars and amino acids within hours to days.
Claim:
In most soils, low-molecular-weight root exudates such as sugars and amino acids are largely consumed by soil microorganisms within hours to a few days after release.
NOT BS
Across most human immune traits, environmental influences explain more variation than genetics.
Claim:
Genetic factors explain more variation in human immune system traits than environmental factors do.
MOSTLY BS
Neptun Deep’s projected plateau output is about 8 billion cubic meters annually.
Claim:
The Neptune Deep project is expected to produce about 8 billion cubic meters of natural gas per year.
NOT BS
Tidal energy follows predictable gravitational cycles, making output highly forecastable.
Claim:
Tidal energy is more predictable than many other renewable energy sources because it is based on a natural, regularly recurring process.
NOT BS
Nursery pig average daily gain is optimized at specific SID methionine-to-lysine ratios.
Claim:
In piglets weaned at 27 days of age, the dietary standardized ileal digestible (SID) methionine-to-lysine ratio has no significant effect on average daily weight gain.
TOTAL BS
DNA and RNA are polymers of nucleotides, each containing a phosphate group.
Claim:
Nucleotides are the monomers of DNA and RNA and each nucleotide includes a phosphate group.
NOT BS
No checks match that verdict.
